Torre del Reloj
Begin under the clock. The Torre del Reloj is the main gate into the historic center and the original entrance to the fortified city that Cartagena still calls the Ciudad Amurallada, standing between the Plaza de la Independencia and the Plaza de los Coches. Before you walk through, look at the façade: a Roman semicircular arch, flanked by two pairs of Tuscan columns, under an entablature with a frieze of triglyphs. The clock that crowns the tower and gives it its name was added at the start of the 18th century.
Locals rarely use that name. To them this is the Boca del Puente, the mouth of the bridge, because a drawbridge once spanned the old San Anastasio canal here and linked the walled city with the Getsemaní neighborhood. The bridge was part of the defense too: when an enemy attacked, it was raised to keep pirates and buccaneers out, while the bastions of San Pedro Apóstol and San Juan Bautista guarded the gate on either side.
The gate is the work of the military engineer Juan de Herrera y Sotomayor, founder of the Academia de Cartagena, and its lines recall the church façade of the San Francisco convent in Santo Domingo. Specialists count it among the most successful works of the Spanish American school of fortification, built strictly along Vauban's principles. Keep Herrera's name in mind; you will meet his work again on the bastion later.
There is nothing to buy and nothing to queue for: it is a passage, open around the clock. Walk through and it is 190 m, about 3 minutes, to the green heart of the old town at the Parque de Bolívar.
