The Mezquita Mosque, now the Igreja de Nossa Senhora da Assunção Matriz, was built below the castle complex in the mid-12th century as a square building with a minaret. After the Reconquista by Sancho II, King of Portugal, in 1238, the Mezquita of Mértola, then supplemented by a small bell tower on the minaret, retained its original form for almost 300 years. In 1532, the Mezquita was converted into a church in its present form, with striking small battlements and turrets on the roof. The original mosque was never destroyed.

In 1982, a major fire destroyed the entire town hall of Mértola, built at the end of the 19th century. In 1984, during reconstruction work, archaeological remains were identified that correspond to the structures of a residential building from the Roman period (1st-4th centuries BC).

The battlements and cones along the edge of the church's roof are striking, clearly a reminder of the former mosque. The interior of the church is rather plain compared to many others in Portugal. However, the vaulted ceiling is very beautiful.
