This two-story building with thick stone walls and an ornate entrance was built in 1743, and for the next 60 years was the headquarters for Brazil's captains (viceroys), appointed by the Portuguese court in Lisbon. When King João VI arrived, he made it his royal palace. After Brazil's declaration of independence, emperors Dom Pedro I and II called the palace home, and when the monarchy was overthrown, the building became Rio's central post office. Restoration work in the 1980s transformed the palace into a cultural center and concert hall. The building houses a restaurant, a bistro, and a bit of shopping. The square on which the palace sits, Praça 15 de Novembro, known in colonial days as Largo do Paço, has witnessed some of Brazil's most significant historic moments: here two emperors were crowned, slavery was abolished, and Emperor Pedro II was deposed. The square's modern name is a reference to the date of the declaration of the Republic of Brazil: November 15, 1889. Praça 15, as it is widely known, sits in front of Rio's ferry terminal and is at the heart of a major regeneration project aiming to transform Rio's run-down docklands.
