Medieval castle, with an oval floorplan and eight quadrangular towers.
Particularly noteworthy is the Pelourinho, the elegant door of the barbican in an ogival arch, the door of betrayal and the Chapel of Our Lady of Ajuda.
Built in Gothic style on a hill and surrounded by the urban network of Vila Nova de Cerveira, it stands out on the left bank of the Minho River, for which it has magnificent views.
In its interior, and in a reasonable state of conservation, one can find the old Governor’s House, the prison and other outbuildings, which were transformed into a hostel which was up and running from 1982 to 2008, with 29 housing units (58 beds), a restaurant, a bar and a conference room. These areas, now vacant, have all the necessary conditions for opening an accommodation establishment (the accommodation units have sufficient area to meet the minimum values currently required for a 5-star hotel).
