Pierre Turquaise, Neolithic burial site in Saint-Martin-du-Tertre, France.
The covered passage stretches over 12 meters in length and 2.5 meters in width, with sandstone slabs weighing up to 18 tons forming its structure.
In 1755, the archaeological structure was emptied and converted into a kennel for hunting dogs belonging to the Prince of Conti.
The monument exhibits carved reliefs on its entrance pillars, including a representation of a double-rank necklace above a pair of breasts.
The archaeological site is accessible through the GR 1 hiking trail in the Carnelle forest, approximately 2 kilometers from the center of Presles.
A complete replica of this largest prehistoric monument in the Ile-de-France region is displayed at the National Archaeology Museum in Saint-Germain-en-Laye.
