Dolmen des Pierres-Gouffier

The present site has three large schist slabs, one of which is set vertically. On one of the two slabs lying flat, the former position of the commemorative plaque of a monument is still visible. The megalithic character of the site is not in question, but nothing allows it to be asserted that it was a dolmen.

The site was first reported in 1863 by the archaeologist Louis Rosenzweig under the name dolmen des Pierres Gouffier, and he mentioned it again in a lecture at the Sorbonne in 1868. According to Rosenzweig it was a destroyed dolmen. In 1889 Joseph-Marie Le Mené placed the Pierres-Gouffier near the hamlet of La Saudraie.

In his inventory of the megalithic sites of the forest of Paimpont, made in 1896, Félix Bellamy does not name the site under this name but records a destroyed megalithic monument called the Trois-Roches, near the Champs Morgan and close to the hamlet of Folle-Pensée. He describes three large flat stones of red schist, one standing and the other two lying at its foot, and he judged that it must have been a dolmen. The table stone, shaped like a very elongated parallelogram, measured about 2.80 m in its greatest length. His description and location correspond exactly to the site shown as dolmen des Pierres Gouffier on the IGN map.

In his inventory of 1994 Philippe Gouezin records, for the commune of Mauron, a former dolmen east-south-east of La Saudraie that was said to have been destroyed by land consolidation. The dolmen de la Saudraie no longer existed as such in 1994, since its stones then formed the monument to the battle of Mauron.
