Catedral San Blas
Begin where the city honours its patron. The Catedral San Blas is the seat of the Diocese of Ciudad del Este and is dedicated to Saint Blaise, patron of both the city and the whole country. Before you head for the door, stand back and take in the full outline: the building was designed to resemble a ship, and once you know that, you will keep picking out the hull and the prow.
The story moves fast, which suits a city this young. Ciudad del Este was founded in 1957, and only six years later, in 1963, the Bolivian architect Javier Quezada was hired to design its cathedral. It was completed in 1964. The church is almost as old as the town around it, built at a time when the place still had to create its own landmarks.
The diocese still marks its big occasions here. In 2023 the cathedral hosted the celebration of the diocese's founding anniversary, attended by the Paraguayan cardinal Adalberto Martínez.
Keep this visit short. The cathedral is free, but after a fire in February 2026 the main nave is temporarily closed, so for now the exterior is the reason to come. Fifteen minutes is enough to walk around the ship slowly and look at it from different angles.
From here it is 670 m, about 10 minutes on foot, to the Museo El Mensú, where the founding years turn from dates into a house you can walk into.
