Arco de São Bento

Arco de São Bento in Lisbon is a stone aqueduct arch that now stands on Praça de Espanha, a short walk from the Calouste Gulbenkian Foundation. It once belonged to the Águas Livres Aqueduct and spanned a street in the São Bento district, beside the Benedictine convent.

What is the Arco de São Bento?

The arch is a remnant of the 18th-century water network that supplied Lisbon. It formed part of the stretch known as the Galeria da Esperança. One source dates its construction to 1758 and mentions long negotiations with the friars of the Convento de São Bento, who were reluctant to give up their land.

Why did it leave São Bento?

In 1937-1938 the building of the then National Assembly, today Portugal's parliament in the Palácio de São Bento, was being remodelled. Modern plumbing had made the old aqueduct redundant, and the arch hindered growing traffic, so the city took it down. Its stones were numbered so it could be rebuilt elsewhere. The project dragged on for decades, and the pieces were kept in municipal storage and, according to one account, in the grounds of the Ajuda Palace.

Where is it now and how do you get there?

The rebuilt arch stands on Praça de Espanha. Sources disagree on when it was re-erected, from the 1980s to 1998, with Lisbon's city council linking the final rebuild to 1998. Take the metro to São Sebastião or Praça de Espanha station. It is a few stops from the centre, close to Eduardo VII Park and the Gulbenkian Museum.

What will you see?

A single, solid gateway of cut stone in plain aqueduct style, with no ornament; its appeal lies in its proportions. It suits a short stop and a photo, ideally combined with a walk to the Gulbenkian or the park. Access is free and the arch is visible at any hour.

Is it easy to confuse with another São Bento?

Yes. The tiled São Bento station is in Porto, and Lisbon's Palácio de São Bento houses parliament. The arch described here is a separate monument tied to the aqueduct.
