At Portas de Montemuro, the landscape stretches out without limits. Here, tables and benches invite you to take a break and enjoy the view, while the national road 321, popular with cyclists, marks the 1,215 metres of altitude. The highest peak of the Montemuro mountain range, at 1,381 metres, is nearby, to the east.
Nearby, the ruins of the Wall of Portas de Montemuro preserve echoes of a distant past. Mentioned in the Inquiries of 1258, they reveal traces of an ancient fortified settlement from the Iron Age, possibly linked to the Castro culture. Later, the site was reused by the Romans and, at the time of the Reconquista, by D. Afonso Henriques, the first king of Portugal.
