Castro de Valongo

Small town located on the right bank of the ribeira de Valongo, which serves as a natural landmark to delimit the parishes of Reigoso and the Village bridge. The most obvious vestiges are the system of fortifications, comprising a moat and three lines of walls.
The first line of wall encircles the upper stronghold, causing a broad platform where if there are some remains of buildings. The second, near the previous one, is well visible and enhanced by a third, in half-moon. West defense is complemented by a wide and deep moat excavated in outcrop.
