Currently only the Banares castle ruins are preserved, situated on the exit road toward Hervias, which allows reconstruction of a rectangular floor plan, with an entrance, facing east, on one of the long sides, flanked by cylindrical turrets, that also reinforce the corners of the rectangle. The walls were of great thickness and sloped. In its interior, one found the keep, attached to the southern section of the wall. Rectangular in form, it was constructed with massive cobblestone and pebble core masonry walls, reaching approximately 3.5 m in thickness. The interior space of this tower is divided longitudinally (E-W) in two naves, by two semi-circular arches which support a square pillar in the center and two corbels on the eastern and western walls.
