Locmariaquer megaliths

The Locmariaquer megaliths are a group of prehistoric monuments located in Locmariaquer, a small coastal town in Brittany, France. The site consists of three main structures: the Table des Marchands, the Grand Menhir Brisé, and the dolmen known as the Er-Grah.

The Table des Marchands is a large stone table measuring approximately 4.5 meters (15 feet) long and 3 meters (10 feet) wide. The table is supported by 10 standing stones arranged in a horseshoe shape, with the tallest standing stone measuring over 4 meters (13 feet) high.

The Grand Menhir Brisé, or the "Great Broken Standing Stone," is a single standing stone that was originally over 20 meters (65 feet) tall and weighed around 300 tons. However, it broke into four pieces and was lowered to the ground sometime in the past, possibly during the Neolithic period.

The Er-Grah dolmen is a burial chamber consisting of two upright stones supporting a massive capstone, which weighs over 40 tons. The dolmen is believed to date back to the early Neolithic period, around 4,500 BCE.

The Locmariaquer megaliths are significant because they are some of the largest and most impressive megalithic structures in Europe. They were constructed during the Neolithic period, around 4500-3300 BCE, and are believed to have had religious and ceremonial significance for the people who built them.
