House of the Viegas Estate, Colonial estate in Senador Camará, Brazil.

The House of the Viegas Estate is a large plantation house with traditional Portuguese architectural features located in Senador Camará in Rio de Janeiro. The building preserves typical colonial construction characteristics including thick walls, high ceilings, and covered galleries that run along the facade.

The first document mentioning the estate dates from 1609; it was the seat of the Engenho da Lapa founded by Francisco Viegas de Azevedo. The main house was remodelled in 1725 and the Chapel of Nossa Senhora da Lapa was inaugurated in 1770. By 1777 the sugar mill was the second most important in the Campo Grande parish, producing 22 boxes of sugar and 1,000 litres of aguardente weekly. The building and chapel were listed in 1938 and restored by IPHAN in 1940–1941.

The estate's name comes from Francisco Viegas de Azevedo, the colonizer who founded the Engenho da Lapa and gave his name to the hill, road and farm. The 1770 Capela de Nossa Senhora da Lapa, attached to the casa-grande and senzala, is still standing. The main entrance opens directly into a large central hall that serves as the distribution point for all side rooms.

Visiting the site requires advance arrangement through IPHAN since it is a protected heritage property. Contact the institution beforehand to confirm access and learn about current visiting conditions.

The house sits on a slope so that its front facade shows two storeys while the side and rear facades show only one. The lower level consists of semi-basements used as storerooms, closed in masonry with doors independent of the house.
