Melgaço Castle currently consists of an imposing keep - with three floors, a parapet protruding over corbels, crowned by pyramidal merlons and with a hipped tile roof - and the surrounding walled enclosure, in a good state of conservation. It is believed that it may have had 3 towers and two doors, according to Duarte de Armas in his “Livro das Fortalezas” (Book of Fortresses) from 1509. The current tower houses the Melgaço Keep Tower Museum.

It is thought that the initial construction of the Church of São Lourenço dates back to the end of the 13th century, but nothing remains of that primitive construction.

From the various chapels that make it up (S. Sebastião, S. João Baptista, Nossa Senhora do Rosário and Nossa Senhora dos Anjos) that of S. Sebastião is also classified as a Property of Public Interest.
