Museu Casa Histórica de Alcântara, History museum in Alcântara, Brazil.

The Museu Casa Histórica de Alcântara is a history museum housed in a colonial mansion at Praça Gomes de Castro. The collection spans furniture, silverware, porcelain, clothing, and accessories displayed throughout multiple exhibition rooms.

The house was recognized as cultural property in 1986 and transformed into a city museum. The collection documents the lifestyle of a family that held importance in the region for generations.

The museum displays how rural aristocracy lived during the 19th century through their furniture, ceramics, tiles, and personal belongings. These objects tell the story of their daily routines and social customs.

The museum occupies the colonial townhouse at number 7, on the corner of Praça da Matriz (Gomes de Castro) and Rua das Mercês, beside the Igreja Matriz and the old Casa de Câmara e Cadeia. The adjoining sobrado at number 15 was bought in 2008 to add a technical reserve, archive, library and rooms for temporary exhibitions. A 2017 project covers both buildings, so parts may be closed while the museum is reconfigured.

The upper floor holds a mirante, a lookout room used to house travellers apart from the family, isolate the sick and watch boats moving in the port. The house also kept enslaved people in separate quarters on both floors: outdoor workers below, domestic servants above.
