Behind the simple facade on Rua das Portas de Santo Antão lies one of the city's most magnificent palaces – a true architectural gem. What now serves as a cultural center and restaurant was originally built in the 17th century as the city palace of the Alverca family. The magnificent rooms, with their Moorish and neo-Baroque elements, speak of bygone splendors. Access to the courtyard in front of the restaurant is free, but in return, quiet and consideration for the "actual" guests are expected. ;-)
