Dolmen de la pointe de l'Herbaudière, Neolithic dolmen at Pointe de l'Herbaudière, Noirmoutier-en-l'Île, France.

The Dolmen de la Pointe de l'Herbaudière is a ruined Neolithic chambered tomb on the sandy shore at the north-western tip of Noirmoutier-en-l'Île, in the Vendée. It is a transept-type dolmen, with a side chamber, now reduced to a few weathered grey and brown slabs: a thick flat capstone with a rounded notch in its left edge lies over a thinner reddish stone, with broken fragments scattered on the sand and dune grass behind.

The monument received official protection as a classified historical site in 1895 after standing for thousands of years on this coastal location. The first scientific examination took place in 1864 and documented the remains of this ancient burial site.

The 1987 excavation uncovered the remains of the cairn around a side chamber, which identified the monument as a transepted dolmen. Only two other examples are known in the Vendée: the Planche-à-Puare and the dolmen de la Guette, both on the Île d'Yeu. The same work found Neolithic flint flakes and pottery sherds on the cairn surface, three of them decorated with punch marks and attributed to the Bronze Age.

Visiting this dolmen depends heavily on tides and weather conditions because coastal erosion affects the structure. It is wise to check tidal times in advance and approach the site carefully.

Archaeological investigations have uncovered pottery sherds and flint fragments from multiple periods on the mound. These discoveries suggest the location served different purposes across a long span of time.
