Castle of Guialmons Monument · les Piles, Conca de Barberà, Tarragona Of Guialmons Castle, around which the settlement of the same name grew up in the municipality of les Piles, only the northwest wall survives, a continuation of that of the church of Santa Maria de Guialmons, behind which its remains stand. The wall stretch is about ten metres long and five metres high, with regular masonry in the first five metres and more deteriorated in the rest. The place is documented since 1080, and the first reference to the castle is from 1132, when Alaric de Timor granted his son Ramon several castles, among which this one figured. In the 14th century it passed to the Boixadors family through the marriage of Francesca de Timor to Berenguer de Boixadors, and later to the counts of Savallà, who kept the lordship until the disentailment of the 19th century.
