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.

This church is actually a monastery, a Dominican monastery. It is dedicated to Blessed Gonçalo, who is also the patron saint of this town. The monastery was built in the 16th century, and parts of it now serve as the town hall and a museum. It's very sustainable.

Very nice cafe on the Ponte de São Gonçalo. Here you can find all the local specialties such as Brisas do Tomega, Papos de Anjo, Foguetes or Bolo de S. Gonçalo. In the cafe you can walk to the river side and enjoy the uninterrupted view of the Rio Tamega and the bridge. When the weather is nice there are also outdoor seats.
