Kerrohet covered walkway (dolmen)

Hidden in the greenery, the covered walkway of Kerrohet, dating back to the 3rd millennium BC, was 12 metres long. Its paved one metre wide corridor still has a part of its cairn. Two covering slabs are also still in place. There are five menhirs and about twenty dolmens on the island of Groix, including the one at Kerrohet and the neighbouring one at Port-Mélite dating back to the 5th millennium BC. They were positioned on a height. They were excavated at the start of the 20th century, but the tombs which had been raided many years previously, provide little information about their date of origin or the dead buried there.
