The Castell de Calaf fortress at the top of a hill

The castle at Calaf dominates the hill above the town and is declared a Bé Cultural d'Interès Nacional. It is considered that this notable fortification was built largely toward the 12th century or earlier in the 13th century.

It controlled the town and the surrounding plains, where two important communication routes intersected - one running north to south through Alt Urgell and Solsonès, and a ramal of the Via Augusta passing through Els Prats de Rei. It is considered one of the most significant fortifications in the comarca, similar to the nearby Castell de Mirambell.
