The Church of Nossa Senhora da Oliveira (1397-1450), belonged to the old medieval monastery. It is the result of a Gothic reconstruction. Between 1450-1515 has undergone important changes at the main chapel, and later in the 17th century was expanded. At that time it was built the bell tower. The biggest relief intervention, which ended up not being completed, was the placing of a broken arc large window of 3 archivolts with historiated frame using Ançã stone, but with a larger scale than the entrance portico.
