Castellet Castle, built on the remains of fortifications dating back more than 2,500 years, was built in 977 with a basic structure consisting of a watchtower and a small wall.
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.
