Marker 5The similarities in construction between the watchtower and the keep date both buildings to the 13th century. The tower, part of the first settlement of the site, served as the advance defences of the original village. Later it found itself at the centre of the site, and from there protected and controlled the one-road village. Its walls are 1.2 m thick and the closing system of the door – with a sliding bar – can still be seen. Probably damaged during a fire, it was transformed into a dwelling with two storeys, separated by a wooden floor that replaced the destroyed vaulted ceiling. The anchorage points for its joists can still be seen in the masonry.
