The recent history of Ruesta is linked to the construction of the Yesa reservoir, which had to be abandoned in 1962 due to a flood. Today it is being reborn thanks to the enthusiastic work of the members of the Confederación General del Trabajo de Aragón, to whom it was ceded in 1988.
The Castle of Ruesta stands out, with the remains of what used to be a Muslim castle. It is a fortification made up of two towers joined by a high stretch of wall, plus another tower which is now in ruins, all protected by a walled enclosure of which only one of the sides is still standing. The main tower is almost square in plan, 8 metres on a side and 24 metres high.
Attached to it by a high stretch of wall topped by battlements is another square tower, about 5 metres on each side, with a few windows and also topped by battlements. Only traces remain of the third tower, although we can assume that it was similar to the others. The walled enclosure that surrounded the whole complex is rectangular in shape, although only one of its sides is still standing and there are traces of the foundations of the rest.
At the exit of the village we find the hermitage of Santiago, dating from the 11th century and cited in the medieval centuries as a pilgrims’ hostel, which may be the explanation for the current presentation.
