This imposing fortress is enclosed by a wall of large ashlars and crowned by a building with towers. It boasts a superb view of the surrounding area.
The most noteworthy remaining features of this castle today are the cylindrical tower and the adjoining Romanesque church, with a peculiar pebble wall. It played an important role in the repopulation of Anoia and overlooked an area rich in natural resources.
The Contrast Tower, dating back to at least the 13th century, is a perfect example of a tower designed as a standalone construction, with a cylindrical form and entrance on the first floor.
The castle of the Tower of Claramunt is one of the few in the Anoia area that is still inhabited. Dating back to the 11th century, the building underwent various extensions in different periods. Its most noteworthy features are its Renaissance-style south and east façades, built at the end of the 16th century.
The most noteworthy features of this 10th castle built on rock are the walls of the Romanesque church of Sant Llorenç, integrated within the fortification.
