That's fascinating! I always find these ancient structures so evocative. It's amazing to think about the people who built them and the lives they led. The description of the capstone and remaining support stones really paints a picture. It's a shame the other stones are lost, but at least there's an excavation with good explanations nearby. Reminds me of a smaller, less known site I saw once - a real "hidden Sprunki" discovery. I appreciate you sharing this! https://sprunkionline.io

Thanks for sharing! I didn't know there were dolmens near Maintenon. https://speedstars.im It sounds like an interesting place to visit, especially with the explanations of the excavation. Do you have more photos of the site?

The Dolmen de la Grenouille https://sprunkedgame.org is a prehistoric megalithic site located in Changé, near Saint-Piat, in the Eure-et-Loir department of France. This dolmen is part of a larger necropolis that includes multiple megalithic structures such as dolmens and a menhir, believed to have been constructed during the Neolithic period around 3500-4500 BCE.

At the edge of this road a pond which forms with the forest which surrounds it a protected natural area. Each year, during the thaw (roughly from February to April), a "toadstool" is installed on the road that runs along the pond. But what is a toaddrome exactly? So, it is not a place where one could indulge in clandestine bets on toad races, but a device intended to prevent these poor beasts from being crushed by cars in crossing the road to breed and lay their eggs in the pond on the other side of the road. Indeed, thousands of common toads, but also frogs and newts, begin their long prenuptial migrations around March each year. They go to the nearest pond or pond to breed. Once their duty is done, they leave the aquatic environment to return to their summering areas where they will spend most of their time feeding. In order to avoid a carnage of amphibians on the road, a tarpaulin is planted 600m on each side of the road to block their passage. In various places a hole has been made in which a bucket is buried. By looking for a passage all along the tarpaulin, the toad will inevitably end up at the bottom of a bucket. Every morning, volunteers come to collect toads and other frogs and drop them off on the other side of the road.

A family and incredible place a few steps from the city center of Rambouillet

The La Drouette river here forms a picturesque lake, surrounded by greenery. It is possible to fish there, to go around it on a hike. How good is it to hike in Île-de-France!

The monuments were erected around 3,500 BC, on a peninsula at the confluence of the Eure and a stream that has now disappeared. The dolmens were built in sandstone blocks coming from 3 km. The sepulchral dolmen, known as “Dolmen Petit”, was covered with a cairn made of limestone blocks. A dozen people were buried in this dolmen. The other dolmen, known as the “Dolmen du Berceau”, was used for ceremonies. He never sheltered a body. This dolmen has remarkable engravings on two of its pillars. The dolmens have been transformed and closed, covered with a huge mound of earth and stones. source: https://www.megalithesdechange.fr/presentation/

The Etang d'Or is formed by the La Drouette river. It is possible to fish there, to go around it on a hike. The pond is pretty and surrounded by greenery.
