An 18th century manor house set in a rural area, located in Agualonga. Its main activity was agriculture, as can be seen by the two existing granaries in front of the house. The building is flanked by a chapel, combining erudite and popular influences, where corners, copings, mouldings and embellishments in granite are prominent.
One of the first owners of the manor house was Esteves da Fonseca Martins, who was responsible for its construction in the 18th century. Later, Casa do Outeiro passed to the Antas family, from Rubiães, as the marriage dowry of D. Francisca Rosa Pereira Antas, given by her uncle.
The last owner of the manor was the Viscount of Peso de Melgaço, and in the eighties of the last century it was donated to the municipality and the diocese.
