Museum Casa Lacerda, Historical museum in Lapa, Brazil.

Casa Lacerda is a stone-masonry townhouse built between 1842 and 1845 in Lapa, with stuccoed interior walls, a two-slope roof, wide rectangular windows and ornamental cornices and friezes. Its sixteen rooms, among them a parlour, dining room, oratory, kitchen, bedrooms, alcove and bathroom, are furnished as a 19th-century Paraná cattle-elite residence.

Built between 1842 and 1845 by the Lacerda family as the home and shop of Manoel Corrêa de Lacerda and Leocádia Cassiana Rezende Corrêa de Lacerda, the house served as headquarters of the 2nd Brigade during the Federalist Revolution. In its main room Colonel Joaquim de Rezende Correia de Lacerda, acting commander of the loyalist forces after General Gomes Carneiro died in combat, signed the city's surrender agreement. IPHAN listed the house in 1938, and SPHAN/Pró-Memória restored it in 1982.

The house keeps its 19th-century campeira elite setting: sixteen rooms including a living room, dining room, oratory, pantry, kitchen, bedrooms, alcove and bathroom, all furnished with period objects. The oratory reflects the family's Catholic practice, and the name "Casa dos Lacerdas" comes from the Lacerda family who built it.

The house stands in the centre of Lapa, Paraná, and can be visited as a museum; the sixteen rooms are spread over a single floor, with the oratory and alcove at the back. Access to the upper floor is not mentioned in the sources, so ask on site about steps and thresholds. The 1982 restoration by SPHAN/Pró-Memória left the original stone masonry and stucco walls visible.

The house served as headquarters of the 2nd Brigade during the Federalist Revolution, and in its main room Colonel Joaquim de Rezende Correia de Lacerda signed the city's surrender act in 1894, after General Gomes Carneiro died in combat. The 1938 IPHAN listing protects the stone masonry and stucco interior walls.
