Every year, Aínsa, in Huesca (Aragón), plays host to this festival of pop, rock and folk music.
This is one of the most important summer festivals in Aragón. Participants include Spanish and international groups, and it features the castle of Aínsa as its main venue. Concerts are also held in other places such as the squares of Plaza de Santo Domingo or Iglesia. In addition to the programme of musical events, there are also exhibitions, street entertainment, workshops and gastronomic tasting events.
