Claramunt castle stands on a hill, dominating the Òdena basin. Its history, marked by wars, is a series of destructions and reconstructions, but despite everything it has managed to conserve its structure and impressive appearance of a fortress. Founded in the second half of the 10th century, it was one of a dense network of castles that marked the border between the county of Barcelona and Al-Andalus.
Their purpose was to protect and organise the territory. The fortress conserves the classical structure of a 12th century castle, divided into two precincts: the residential part, with the hall and the keep, and the upper storey which housed the services required for the maintenance of the castle and today is a great walled courtyard.
