The Church of Santo António has been classified as a Monument of Public Interest since 2012. The church is located in Terreiro de Santo António, in the historic centre of the town. The building is in the Mannerist style, and still maintains the same layout in which it was built. It has a longitudinal plan, with a single nave and two side chapels. The exterior is quite sober in appearance, contrasting with the rich interior, which contains a Mannerist altarpiece in an aedicule, decorated with gilded carvings. It is divided into three parts, with the lower and central parts decorated with scenes alluding to Saint Anthony, while the upper part depicts the Holy Trinity. Other elements of interest include the paintings on the vault of the chancel, in the proto-baroque style, and the set of blue and white tiles, with albarradas, made in the late 17th century. The church was built in the 1640s and was supposed to be part of a convent dedicated to Saint Anthony, but it was never built.
