Castellterçol Main Festival Activity · Castellterçol, Moianès, Barcelona The Festa Major of Castellterçol is held on the fourth weekend of August (22-26 August in 2025), with two traditional Catalan dances as its central events: the Dansa de Castellterçol, on the last Sunday, and the Ball del Ciri, on the following Monday. They are performed by six couples of dancers wearing the traditional 17th-century peasant costume, who formerly represented the outgoing administrators of the year; after Mass, the procession heads to the Church of the Plaça Vella for the dance of the authorities and the sardana, and the next day the same couples dance the Ball del Ciri carrying candles and almorratxas with which they sprinkle the public. The village also holds a winter festa major, on 21 January, dedicated to Sant Fruitós, with the burning of the Christmas tree in the Plaça Vella. 28-29 d'agost Photo: Pablondelpms (CC BY-SA 4.0) What to see and do in Castellterçol
