Galerias Romanas da Rua da Prata

The Galerias Romanas da Rua da Prata are a remarkable archaeological site tucked beneath the bustling streets of Lisbon's Baixa neighborhood. These subterranean galleries, dating back to the 1st century AD, were part of a Roman cryptoporticus, a structural support system for the forum above. Today, visitors can descend into a maze of vaulted chambers and corridors, where the original stonework and a section of the Roman aqueduct are still visible. The site is only open to the public a few times a year, typically during the city's Heritage Days, adding an air of exclusivity to the visit. The experience is immersive: the cool, dimly lit space contrasts sharply with the vibrant city above, offering a tangible connection to Lisbon's ancient past. The galleries are a must-see for history enthusiasts and anyone curious about the layers of civilization beneath modern Lisbon.

A bit of history

Built in the 1st century AD during the Roman occupation of Olisipo (modern Lisbon), these galleries formed a cryptoporticus that supported the city's forum. Rediscovered in the 18th century after the 1755 earthquake, they were later used as a water cistern. Today, they are a protected archaeological site.
