    Mainz Cathedral

    Mainz Cathedral, stop 1 on the self-guided walking tour

    You start in front of a building that has stood here for a thousand years. Mainz Cathedral, the Dom, is Romanesque at its core, but centuries of later additions have layered other styles onto the outside, so it reads like a history book in stone. Officially it is the Hoher Dom zu Mainz, dedicated to Saint Martin of Tours; the eastern quire belongs to Saint Stephen. Look out for the statues of Saint Boniface and the Madonna on the grounds, and for the inner courtyard.

    The man behind it is Archbishop Willigis. Under him Mainz flourished, and he became one of the most powerful politicians of his age, even acting as regent of the empire between 991 and 994. Shortly after taking office in 975 he ordered a new cathedral as part of his vision of Mainz as a “second Rome”. It was meant to replace two churches at once: the old cathedral and St. Alban's, the great abbey church where synods met and where bishops and nobles were buried, among them Fastrada, a wife of Charlemagne.

    Willigis's church had a double chancel with two transepts, a three-aisled nave without vaults, since a vault on that scale was too difficult to build, and six towers. A cloister was enclosed in the complex, and a colonnade linked it to the small St. Mary's Church.

    Go inside: it is free, and everyone gets something from it. The tombs and funerary monuments of the elector archbishops, the prince-bishops who ruled Mainz, line the interior, along with religious art spanning a millennium. Half an hour is enough.

    Mainz's weekly market, the Wochenmarkt, is right here at the start. Then it's 620 m, about 9 minutes, to the Gutenberg Museum, passing the Naturhistorisches Museum Mainz on the way.

    Gutenberg Museum

    Gutenberg Museum in Mainz, stop 2 on the self-guided walking tour

    Mainz is the city of Johannes Gutenberg, the man who brought printing with movable metal type to Western Europe, and this is the museum that bears his name. It is one of the oldest museums of printing in the world, and its collections reach far beyond Gutenberg himself: printing equipment and printed material from many cultures, the history of writing worldwide, book art, posters, paper and modern artists' books.

    It was founded in 1900 by a group of citizens, 500 years after Gutenberg's birth. Publishers, printing houses and makers of printing machines donated books and equipment to start the collection. At first the museum was part of the city library and filled just two rooms in the Electoral Palace, which meant the finest volumes from the library could simply be borrowed: visitors saw almost 500 years of the printed book. In 1912 it moved with the library to the Rheinallee, and in 1927 into the building Zum Römischen Kaiser, dating from 1664.

    The crowd-puller since 1925 has been the reconstruction of Gutenberg's workshop, which made type founding, typesetting and printing visible. The replica press was rebuilt from 15th and 16th century woodcuts and travelled to exhibitions all over the world.

    This is the one paid stop on the walk. If books, type or the birth of mass media interest you even slightly, give it an hour or more; if you're tight on time, it's the stop to shorten.

    From here the route heads down to the river: 850 m, about 12 minutes, to the Rhine Promenade.

    Rhine Promenade

    Rhine Promenade in Mainz, stop 3 on the self-guided walking tour

    After cathedral and museum, the route leaves the stone behind and the mood changes completely. The Rhine Promenade has no gate, no ticket and no closing time: it is an open public space, and in summer the riverbank itself, not any building, is the reason to come.

    Two things to know about the water. The Rhine is a working river with a strong current and commercial shipping, so swimming is not an option; watch the barges instead. Between May and September the promenade is Mainz's social artery, and the city uses it most in the evening.

    Timing decides what you get here. In high summer the promenade and the stone streets of the Altstadt radiate heat at midday; the comfortable hours outdoors are before ten in the morning and after six in the evening. If you pass at noon, keep this stop short and come back later: around sunset, the view across the river toward Wiesbaden is the one worth pointing your phone at, most reliably from May to August.

    From the river it's 720 m, about 10 minutes, back into the Old Town to the Kirschgarten.

    Kirschgarten

    Kirschgarten in Mainz, stop 4 on the self-guided walking tour

    The Kirschgarten is the Mainz of postcards: a small square framed by rows of half-timbered houses from the 15th to the 18th century. The name, “in the cherry garden”, is recorded as early as 1329, but it comes from a spring, the Kirschborn, that rose by the old Rochus hospital. Under French rule around 1800 the city map translated it into Jardin des cerisiers.

    For a long time this was a closed square, opening onto the Augustinergasse only about one house wide, and it lay within the immunity of the cathedral chapter. It belonged to the Nova Civitas, the town's expansion in the 13th and 14th centuries, and the Swedish plan of 1625/26 shows it densely built. Only at the end of the 18th century was the lower lane widened into today's square, with a link to Schönbornstraße. Between 1976 and 1979 the houses were thoroughly restored and their timber framing uncovered.

    Fresh from Gutenberg, note that printing continued here: in the late 16th century Johann Albinus ran a print shop in the house “zum Sewlöffel”, the sow's ladle, founded by Friedrich Heumann. And look for Haus Zum Aschaffenburg, built around 1500 and the oldest half-timbered house in Mainz that still partly survives.

    The fountain in the middle dates from 1932, a gift from a local beautification society. Its red sandstone came from decorative parts removed from the road bridge. On top stands a copy, by Jean Sauer, of the Harxheim Madonna; the relief at its base by Carl Moritz Hoffmann shows the Blasius chapel, which formed the entrance to the Kirschgarten until 1803.

    The next stop is practically next door: 140 m, about 2 minutes, to the Augustinerstraße.

    Augustinerstraße

    Augustinerstraße in Mainz, stop 5 on the self-guided walking tour

    The Augustinerstraße is the main street of the southern old town and one of the busiest pedestrian streets in Mainz. Its roughly 270 metres are a protected monument zone, and the whole street lies inside the line of the Roman city walls. It takes its name from the Augustinian hermits, who built a monastery here in the 13th century.

    Until the 17th century this was the main shopping street of Mainz. Then the Thirty Years' War hit hard: a survey of 1657 describes the street as a “wuster hausplatz”, a wasteland of house plots. Afterwards many long, narrow plots with slim half-timbered houses were merged into larger ones, but the rough layout of the street survives to this day.

    Look closely and older layers show through. Remains of upper-class courtyards from the late Middle Ages survive, and some newer buildings reuse old walls: number 26 incorporates parts of the court “Zum Großen Drachen”, the Great Dragon. Stone mullion windows and vaulted cellars already appear on the Swedish plan of 1625/1626.

    The tallest and most striking building is the Augustinerkirche, built between 1768 and 1776, when the street was home mainly to craftsmen and traders, above all tailors and shoemakers. The monastery was dissolved in 1803, and in the mid-19th century the street got a new, wider building line when the Kartäuserstraße was laid out.

    Now the route switches to Roman Mainz: 610 m, about 9 minutes, to the Roman Theatre.

    Roman Theatre

    Roman Theatre in Mainz, stop 6 on the self-guided walking tour

    What you see here was only excavated in the late 1990s, right next to the Mainz Römisches Theater station. This was once the largest Roman theatre north of the Alps: 116 metres across, with room for roughly ten thousand people. It is open around the clock and free, so you can look in at any hour.

    Roman Mainz was Mogontiacum, and its importance came from its position where the Main meets the Rhine. From 13/12 BC a double legionary camp stood here, a base for defending the frontier, the limes, and for campaigns against the Germanic tribes. A civilian settlement grew next to it and became the capital of the new province of Germania Superior around AD 80.

    The theatre was probably closely tied to the funerary games for the general Drusus, whose cenotaph stands only 340 metres away. Military parades were held there in his honour from 9 BC, and delegations of the sixty Gallic communities may have used the theatre for their thanksgiving ceremony. Suetonius mentions a theatre at Mogontiacum in his account of the year AD 39, and the stone building you see was probably preceded by one made of wood.

    Its end came from its own stones: when the city wall was built in the mid-fourth century, it was quarried for material and left outside the walls to decay. Only its massive vaults lasted a few more centuries.

    It's a short 310 m, about 5 minutes, up the Jakobsberg to the Mainz Citadel.

    Mainz Citadel

    Mainz Citadel, stop 7 on the self-guided walking tour

    The Zitadelle sits on the Jakobsberg at the edge of the Old Town, built in 1660 as a key piece of the Fortress Mainz. Before the soldiers came, a Benedictine abbey had stood on the hill since 1050, and halfway up, the remains of the Roman theatre must still have been visible.

    The problem was strategic. The hill lay outside the city walls, right at the town's gates, so an attacker could use it to raid Mainz or bombard it. Between 1620 and 1629 the cathedral vicar Adolph von Waldenburg closed the gap with the Schweickhardtsburg, an irregular pentagon named after the reigning elector Johann Schweikhard von Kronberg. Around 1655 Elector Johann Philipp von Schönborn had the whole town refortified with French-style bastions, and the pentagon became the regular, four-sided citadel you walk through today.

    Look at the gate facing the town: in 1696 Lothar Franz von Schönborn had a commander's building raised above it, skilfully absorbing the gateway that had existed since 1660. The abbey and the Roman Drususstein were left standing inside the walls. During the siege of 1793 Prussian shelling largely destroyed the abbey, and a map of 1804 shows a Baroque garden in the south of the courtyard. In 1816, after the Napoleonic Wars, Mainz became a fortress of the German Confederation.

    The grounds are freely accessible and free. If fortifications are your thing, there is a two-hour guided tour, “Festung Mainz”, with the Garrison Museum, which costs extra. From the citadel it's only 90 m, about 1 minute, to the Drususstein.

    Drususstein

    Drususstein in Mainz, stop 8 on the self-guided walking tour

    The plain tower of masonry in front of you, nearly 20 metres high, is one of the few visible remnants of Roman Mogontiacum. It was once cased in marble, and researchers now largely accept that it is what remains of the cenotaph raised in 9 BC for the general Drusus.

    Drusus, stepson of Emperor Augustus, had founded the legionary camp here opposite the mouth of the Main no later than 13/12 BC, as a springboard for conquering Germania. He died during the campaign of 9 BC. His brother Tiberius and the army brought his body back to Mogontiacum, and before it was taken on to Rome, the soldiers held a memorial ceremony. That is when the wish arose, apparently spontaneously, to honour their popular commander here with a permanent monument.

    In the early days of the empire this was the centre of the imperial cult in the city and the starting point of elaborate memorial ceremonies, with a procession road linking it to the theatre you've just seen, probably on the day of Drusus's death and on his birthday too.

    Its later life was less dignified. Stripped of its marble in the early Middle Ages, it served as a watchtower in the town's fortifications in the 16th century, and a doorway was cut into what had been a solid block. Together with the Igel Column, it is the only ancient funerary monument north of the Alps still standing in its original place.

    Leave the citadel for the last church of the walk: 730 m, about 10 minutes, to St. Stephan.

    St. Stephan

    St. Stephan in Mainz, stop 9 on the self-guided walking tour

    St. Stephan is the church most people come for because of Marc Chagall: his windows have made this Gothic collegiate church known well beyond Mainz. The church itself is worth the visit too, and besides the cathedral it is the most important church in the city.

    You've met its founder already. Archbishop Willigis had it built in 990 on the highest hill in town, most likely on behalf of Theophanu, widow of Emperor Otto II; a charter of Otto III from 992 describes it as standing “at the summit” within the walls. Willigis meant it as a place of prayer for the empire.

    The present building is late medieval, begun around 1267 and finished in 1340, yet it kept the double-choir plan of the original. It is the oldest Gothic hall church in the Upper Rhine region: three naves of equal height, choirs at both ends, and a large octagonal bell tower over the western choir. The cloister was added on the south side between 1462 and 1499.

    Its scars are visible if you look. In 1857 the explosion of a nearby powder magazine destroyed the Baroque facing, and the bombing of World War II damaged the church heavily. The vaults over nave and choir could not be saved and were replaced by the flat wooden ceiling you see now; the cloister and the western belfry were restored between 1968 and 1971.

    Go in: it's free and twenty minutes are enough. Then it's 830 m, about 11 minutes, to the final stop, the Isis and Magna Mater Sanctuary.

    Isis and Magna Mater Sanctuary

    Isis and Magna Mater Sanctuary in Mainz, stop 10 on the self-guided walking tour

    The walk ends with a surprise in an unlikely place: a Roman temple underneath a shopping arcade. In the late 1990s the postwar Lotharpassage was demolished to make way for a new shopping centre, and a large pit was dug. Archaeologists expected the usual: the Roman road from the legionary camp to the Rhine bridge ran through here, so they reckoned on half-timbered row houses with small workshops.

    Instead, in late 1999, at a depth of about five metres, they found a sanctuary that inscribed blocks identified as belonging to Isis Panthea and Magna Mater, built in the 1st century and used into late antiquity. Beneath it lay a burial from the Hallstatt period, about 700 years older. Over 17 months the site was excavated in detail: 15 tonnes of soil were taken for plant and animal analysis, and 49 cubic metres of finds were recovered before the work ended in early 2001.

    The plan was to document the walls and then remove them for the mall. Public protests stopped that. Instead, a display room was created on the spot, the Römerpassage was built around it, and the key architectural remains and selected finds are now shown in a permanent exhibition. A full scholarly publication of the excavation is still pending, so what you see here is the best account there is.

    Admission is free. A quiet, slightly eerie ending after the open air of the theatre and the citadel, and worth twenty minutes.

Shorter ways to walk Mainz

Not everyone has a full morning. The route splits cleanly into an Old Town half and a Roman half, and each works on its own.

Old Town and Gutenberg

Stops: 1, 2, 3, 4, 5

For first-time visitors who want the cathedral, printing history and the half-timbered lanes. About 33 minutes of walking; the only admission is the Gutenberg Museum. With the museum and the cathedral interior, count on about three hours.

Roman Mainz and Chagall's windows

Stops: 6, 7, 8, 9, 10

For history fans who already know the cathedral: theatre, citadel, the Drusus monument, St. Stephan and the Isis sanctuary. About 27 minutes of walking, everything free, and done in under two hours.

How long this Mainz tour takes with museum and churches

The pure walking time is 1 h 8 min for 4.9 km, and no leg is longer than 12 minutes. What stretches the day are the interiors: half an hour in the cathedral, about 75 minutes in the Gutenberg Museum, around 20 minutes each in St. Stephan and the Isis sanctuary.

A realistic plan: start at the cathedral at 09:00, reach the Gutenberg Museum around 09:40 and leave it just before 11:00. The river, the Old Town lanes and the citadel fill the next two hours, so you arrive at St. Stephan close to 13:00 and at the sanctuary around 13:30, finishing before 14:00. That order also means St. Stephan and the sanctuary are open by the time you get there.

Before you set off in Mainz

  • Start and finish: The recommended start is Mainz Cathedral, the finish is the Isis and Magna Mater Sanctuary. You can join the route at any stop; the order given is simply the one that works best.
  • Best day: Pick your day with care: the sanctuary does not open every day, and on some days the cathedral and St. Stephan open later.
  • Time of day: Starting early in the morning lets you see every interior in order. Don't start after midday if the Chagall windows in St. Stephan matter to you.
  • Costs: The walk itself and almost every stop are free; the Gutenberg Museum charges admission. The GPS route and map are free. The AI Tour Guide comes with 100 free credits; after that you choose between this tour all-inclusive for €19.99 with no time limit, or credits at €5 per hour.

Common questions about walking Mainz

Where does the walk end, and how do I get back to the cathedral?

It ends at the Isis and Magna Mater Sanctuary in the Römerpassage. If you want to return to the start, the GPS navigation in your browser leads you back to Mainz Cathedral on request.

Is the Isis sanctuary open every day?

No. It has closing days, public holidays and carnival among them. If it is shut when you visit, enjoy the Roman half of the route outdoors and skip the final stop.

Which cities near Mainz make a good second day?

Wiesbaden is only 10 km away, Frankfurt 31 km. If you liked the cathedral, the imperial cathedral cities of Worms and Speyer continue the story along the Rhine.

Is there more Roman Mainz than the stops on this walk?

Yes. Apart from the theatre and the Drususstein, pillars of the Roman aqueducts are among the few visible remains of Mogontiacum. They are not on this route, so add them separately if Roman history is your main interest.

Is the tour really free?

Yes. The whole tour is free: the route, the interactive map and the navigation cost you nothing. Only the voice AI Tour Guide is optional and paid: you test it with 100 free credits, then you pay either €5 per hour or €19.99 for this whole tour, with no time limit.
