Ribeira Palace (Portuguese pronunciation: [ʀiˈbɐi̯ɾɐ]; Portuguese: Paço da Ribeira) was the main residence of the Kings of Portugal, in Lisbon, for around 250 years. Its construction was ordered by King Manuel I of Portugal when he found the Royal Alcáçova of São Jorge unsuitable. The palace complex underwent numerous reconstructions and reconfigurations from the original Manueline design, ending with its final Mannerist and Baroque form.
The Ribeira Palace, as well as most of the city of Lisbon, was destroyed in the 1755 Lisbon earthquake. After the earthquake, the reigning monarch, King José I, suffered from claustrophobia and chose to live the rest of his life in a group of pavilions in the hills of Ajuda, and thus the palace was never rebuilt.
Today, Lisbon's primary square, the Praça do Comércio, is situated on the site of the former palace. The square is still popularly referred to as the Terreiro do Paço, reminiscent of the now destroyed royal residence.
After the Siege of Lisbon, in 1147, the monarchs of Portugal had used the Palace of Alcáçova, in the Castle of São Jorge, as their residence while in Lisbon, which did not become Portugal's definite capital until 1225. Over the years, various Portuguese monarchs added to the Palace of Alcáçova, and by the time King Manuel I of Portugal succeeded the throne, the Palace of Alcáçova was a large, but cramped, complex, not fitting with the tastes of King Manuel I. With his lucrative profits from Portugal's monopoly on the spice trade, King Manuel I set off on a building spree, renovating the Lisbon landscape, and starting with the construction of a new royal palace.
