In early April we were fortunate, as members of the Terras D’Ossa Association, to be invited to take part in a guided tour of Vila Viçosa. The theme of the walk was the use of marble in religious buildings in the town—churches, convents and other religious monuments. You may think this sounds like it could make for a boring morning, but far from it!

Although this monument is a little way off from Estremoz, the Anta Tapadão at Aldeia da Mata really is worth a visit as it is one of the most accessible and complete dolmens in the country.

An hour’s drive north from town, Aldeia da Mata is a small village in the Portalegre district. As you draw close huge rock formations begin to appear in the surrounding fields – some even used as fences or outbuildings by local farmers – conjuring up an ancient medieval atmosphere before you arrive at the historic site.
