Menhirs Jean et Jeanne, Prehistoric standing stones in Sauzon, France.

Jean and Jeanne are two menhirs standing about 340 metres apart east of Kerlédan, along the D25 road in Sauzon. Jean is a stone block of roughly 3 metres with a quadrangular section; Jeanne is a block of about 3.50 metres with a clearly visible fracture face. Both are classified historical monuments.

These standing stones date back to the Neolithic period and were officially classified as historical monuments in 1943. The original pair was destroyed in 1830 when people took them apart to use the stone for building walls, and what we see today was erected afterward.

The names Jean and Jeanne were given by cartographers to these two stones, recalling two earlier menhirs of the same names at Runelo that were broken up around 1840 to build the walls of a property at Kersantel. The historian Chasle de La Touche noted in 1852 that the two fine menhirs had been smashed for the farm walls.

The stones are accessible directly from the D25 road and can be visited at any time. There are no facilities or special infrastructure at the site, so wear sturdy footwear and be prepared for a simple visit in open countryside.

The current stones were named after two earlier menhirs at Runelo, destroyed around 1840 and used to build walls at Kersantel. The original Jean was 3.60 m of red schist; the original Jeanne, about 7.90 m tall, was described as granite but seemed not to be local rock.
