Praça do Comércio
The striking plaza close to the River Tagus is the largest square in Lisbon. The bright yellow buildings that surround the Praça do Comércio make this landmark unique, and attract plenty of tourists and photographers. The area once held the royal palace after the Portuguese royalty left the Castelo de São Jorge, but it was destroyed in the Lisbon earthquake in 1755, with the square built in its wake. Today, it’s home to the Rua Augusta Arch, designed by the Portuguese architect Santos de Carvalho and completed in 1873. The buildings that circle the square hold a few government buildings, including the tourism office, as well as one of the hottest Lisbon nightclubs, several restaurants and a sophisticated winery. The square also goes by the name Terreiro do Paço and is known as “Commerce Square” in English.
