The castle sits on top of a hill and is small, in exposed stone. It has a watchtower, a square tower, a single door and a cistern. The roof and battlements of the watchtower were rebuilt in the 20th century.
The climb is on foot from the town, a steep but easy slope. Anyone who wants to reach the top floor of the square tower faces a difficult last stretch: wear closed shoes and take your time.

The town of Basto, down below
Before 1717, the town at the foot of the castle was the seat of the municipality. You can still see restored houses and a pillory next to the interpretation centre, housed in the old primary school. On a path that climbs beside a vineyard stands the old gallows, restored in 1963, with a view over the town and the castle.
About 3 km from the castle, as the crow flies, stands the Monastery of São Bento de Arnóia: a granite church with a single nave, a square bell tower and a cloister. We found no published visiting hours. to be confirmed
