Damenhill
This huge igneous rock, named Grand-Menhir, is a granite with a height of 20 meters and a weight of more than 280 tons. The engineering technology used to move and erect such a huge stone is impressive, especially since the nearest source of this stone is 10 km. At the end of the arrangement of 18 interlocking stone c, we can carefully locate the door hill with slope. It was destroyed in 4500 BC, but it is displayed on this site today. Use a timely hammer to finish the door hill and give it a smooth surface. Another huge standing stone or tablet once stood near the huge stone, two of which-marked by their cow carving-were reused near the grave (see below) and the stone grave on the small island of Nice, Gaffry, 4 kilometers away from Mobien Bay. The surface of the Grand-Menhir is engraved with carefully designed nail marks, and there is a socket at the bottom of the stone to increase the stability when standing. However, the giant then fell down and broke into four pieces. It is not clear whether this is caused by natural causes such as strong winds, lightning or earthquakes, or by man-made destruction. More importantly, the fall is likely to happen hundreds of years after his erection, about 4000 BC.
Because the soil is acidic, no human remains were found in the tomb, but flint tools, jewelry and ceramic plates were found in the excavation.
El-Gerlach Tomb
Er-Grah Tomb (or Er Vinglé means "quarry" in the local Brittany language, and indicates the future role of this site as a source of building materials), just a few meters away from Grand-Menhir, probably built around 4200 BC. Single tomb is140m long and16m wide. Trapezoidal, relatively moderate height, no more than 2 meters. Since 4500 BC, this structure has evolved over time, forming a group of small tombs, mounds, ditches and some houses. Later, a rectangular stone tablet was built on the site, including a huge slate as the roof, which is still a part of the structure today. In 4000 BC, limestone was used to cover the surface matching the existing stone, thus expanding the stone tablet. Because the soil is acidic, no human remains were found in the tomb, but flint tools, jewelry and ceramic plates were found in the excavation.
Biao de marchand tomb
This stone tomb named table-des-marches was built around 4000 BC. The name of the monument (merchant's table) comes from the huge stone slab incorporated into the roof of the inner room (stone tomb), with a size of 7×4 meters and a thickness of 80 cm. In fact, this slate was completely excavated during the Roman period. Time is also a part of the stone, and the other piece is used in the ancient tomb in Nice, Gaffry. Locmariaquer's stone pier is 30 x 25 meters in size, but now its height is less than half of its original height. The inner stone tomb and entrance corridor are composed of large flat vertical stones, with horizontal slates and dry masonry at the top. Over time, corridors allow more graves to be added to graves. The inner tomb is 2.5 meters high and impressive, including the large pointed stone facing the entrance, which is considered to represent the gods. This huge sandstone stone tablet is covered with linear relief, which was originally set near Grand-Menhir and then used in ancient tombs. Other carvings on the inner stone include a liar, a cow and an axe.
