context_page_description: The Church of Nossa Senhora da Anunciação is a 12th-century church and former mosque in the civil parish of Mértola in the municipality of Mértola, in the Portuguese Alentejo.
context_section_description: The church is located on an isolated hilltop, implanted on the steep slopes below the Castle of Mértola, but dominating the northern aspect of the town, on terraces above the Guadiana River. Its principal facade is situated along a roadway delimited by wall across (PT040209040017), and nearby the Chapel of Calvário.
  The plan consists of a large, rectangular nave, rectangular annex (in the north), a pentagonal mihrab (in the east) and a square bell tower (in the southeast) all covered in differentiated tile roof. The four facades are crowned by triangular staccato merlons, alternating along the lateral walls with conical pinnacles and chamfered merlons. The principal facade, oriented on an angle to the south, one of the pinnacles acts as decoration and cylindrical buttress (in the left corner), adjoining the prismatic bell tower with windows in the upper section and fogaréus in the four corners.
  Attached to the middle axis of the facade, is a three-storey buttress of differing molding that ends in a conical pinnacle. To its right, in decentered position, is a rectangular portico framed by low relief and colonnades, surmounted by molded oculus. On the rear facade, is a prismatic annex and an oblique archway portal framed by alfiz. On the right lateral facade is the faceted volume of the mihrab. Several buttresses reinforce the main elevation and the lateral elevations, one of them disposed in a diagonal, another flying buttress.
