The Landevennec abbey
The Landevennec abbey is a historic monument at the entrance to the Crozon peninsular that you can’t miss. Near the site of the former abbey, the museum, whose collection received the “Musée de France” appellation in 2017, traces the history of the monastery from its foundation to the 18th century.
