In its old town there is a beautiful castle of Arab origin and about five kilometers from the town is the beautiful monastery of Bellpuig. But the prize goes to the Cova dels Vilars, a cave a few meters from the town center with cave paintings that has been declared a World Heritage Site.

Agricultural and cattle town with a united community. Legend has it that on top of the reddish rocks that preside over the town lived a dragon (or some kind of winged monster) that devastated the crops. One night of San Juan, the neighbors rebelled against Dugo, the dragon, they set fire to his cave and killed him. Next to his cave there was a small castle, which together with the reddish color of the rocks created the name of Castillonroy.
