Church of the old Convent of Santa Ana, of Benedictine nuns, built by the local nobility with the support of the City Hall, to house the daughters of the Viana nobles who eventually did not marry. The primitive convent, with Gothic roots, was the work of Pero Galego, who lived in Caminha, where at the dawn of the 16th century he directed the second phase of the work on the main church. After some expansion works carried out at the beginning of the 18th century, it was between 1897 and 1905 that the main renovation works of the convent building were carried out, resulting in a grandiose architectural complex that preserved the frontispiece of the 18th century church in the “Joanine Baroque” style and which reused the magnificent Manueline spire in the tower.

Female Benedictine monastery founded in 1510, of which the Manueline tower remains, some capitals of the cloister and a portal, displaced. At the end of the 16th century, the cladding with checkered tiles in the church and in the high choir and the pews in the main choir still date.
The church was rebuilt between 1707 and 1737 in Baroque style, whose hallmark was, among others, the carving of the altarpieces and the pulpit, the high choir’s stoned chairs and the decoration, altars and tombs of the chapter hall, now the sacristy.
Nationalized, it was transformed by this Congregation into a nursing home in 1905. At that time, the tower was moved, destroying the lookout and a balanced building was built with an eclectic design dominated by a graceful neoclassical style.
