Grand Cairn de Barnenez

Built 6,000 years ago, this monument is 75m long and 28m wide, and stands as a testament to an unexpected level of engineering know-how. Eleven corridor tombs are hidden within its titanic facade, some of which bear engraved messages that have yet to be understood.
Don’t miss this Neolithic masterpiece, nicknamed ‘the Prehistoric Parthenon’ and considered the oldest mausoleum in Europe!
