The church of Sant Elies in Mediona, which was first documented in 1301, could be Romanesque, according to the historian and writer Esteve Cruañes

Claramunt Castle stands at the top of a hill, overlooking the point where the gorge of the Anoia river opens into the Òdena basin.

A castle from the 10th century, with a Templar construction from the 13th century and two towers from the 15th century, encased on the old road from Sant Quintí to Sant Joan de Mediona, it guarded this strategic enclave for centuries.
