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.

With a widely recognized hunting history and approximately 90% of its territory designated as a game reserve, Mértola is today undoubtedly the national capital of the art of hunting (Capital da Caça) in Portugal. This beautifully designed monument is dedicated to this art.

I have already visited the outskirts of Mértola on a hike that I really enjoyed, an area of short bushland, along well-marked trails. Good food and with many historical elements of Islamic culture. Relatively close by, we have the Mina de S. Domingos, where we also had an excellent hike, where you can see the remains of the old mines. We can also visit the village, with many skills from the workers of the old mines. I recommend it.👍🇵🇹
