Origin and history

The Dolmen and Polishoir de Haute Bretagne, also known as the Dolmen des Hauts de Bretagne, is located in Huisseau-en-Beauce, in the department of Loir-et-Cher. This megalithic monument dates from the Neolithic and consists of a dolmen with portico and an adjacent polisher. The dolmen, now ruined, had a rectangular chamber of 3.80 m long by 1.80 m wide, facing east/west, preceded by a portico with supports of 0.60 m high. The roof tables of the room were dynamited at the end of the 19th century, leaving slabs in sandstone and puddingue glossed with local flint.

The polisher, a 1.70 m x 1.50 m glossy sandstone block, features a groove, five bowls and a polishing range. In 1974, it was located near the dolmen bedside slab. These elements are evidence of artisanal and ritual use during Neolithic, a period marked by the emergence of agriculture and complex community structures in Europe.

Ranked as historical monuments since 1889, this site illustrates the importance of megaliths in the prehistoric heritage of the Centre-Val de Loire region. Local materials (stone, puddingue) and polishing technique reflect the expertise of neolithic populations, while partial destruction in the 19th century highlights the challenges of preserving ancient remains.
