Dent de Gargantua

Dent de Gargantua is a Neolithic quartz stone standing upright in the Brittany region, with four distinct sides and varying widths on different faces. The monument sits near the mouth of the Rance River estuary.

The stone was erected during the Neolithic period and remains one of the oldest structures in the region. The French government formally protected it as a classified historical monument in 1889.

The site draws its name from a legend about a giant who lost a tooth, a tale that still shapes how local people speak about the stone. This story remains woven into the place's identity and guides how visitors understand what they see.

The site sits on private property, so visitors need to arrange permission before accessing it. It is best to check local conditions ahead of time and view the stone from nearby public areas if direct access is not available.

Two other megalithic structures once stood in the area as part of the same ancient group, though they have disappeared over time. These lost stones reveal that the region once had a much richer landscape of standing monuments.
