The Catedral San Blas is the Roman Catholic cathedral of Ciudad del Este and one of the few buildings in the city centre that has nothing to sell you. Dedicated to Saint Blaise (San Blas in Spanish), the cathedral sits a short walk from the commercial chaos of Avenida San Blas — a geographic irony that locals seem to enjoy.
The interior is cool and quiet, a useful refuge from the heat and noise outside. The building itself is modern and not especially distinguished architecturally, but it offers a moment of calm that is otherwise hard to find in this city. Mass is held several times daily; if you are passing through and need a few minutes of peace before catching a bus or crossing the bridge, the cathedral is the place to find it.
