Castle of Freixe Monument · Piera, Anoia, Barcelona Freixe Castle stood on a hill near Can Freixe, on the left bank of the river Noia, in the southern sector of the municipality of Piera, as part of the Christian resettlement that took hold in the comarca in the 10th century. The place is mentioned in 955 in a resettlement charter of the viscount of Barcelona Guitard; the circular tower, probably from the 11th century, was attached to the Romanesque church of Sant Nicolau de Freixe. In 1041 Viscountess Riquilda ceded her possessions in Freixe to her son Guislabert, bishop of Barcelona, and the castle later passed to Santa Maria de Solsona; in 1386 the infante Joan sold its jurisdiction to Berenguer de Tous. The surviving tower is about 5.4 metres in external diameter and today reaches 6.5 metres in height, built of irregular pebbles. Photo: Antoni Grifol (CC BY-SA 3.0) What to see and do in Piera
