Carnac stones

The Carnac stones are a collection of over 3,000 ancient standing stones located in Brittany, France. Believed to have been erected around 4500 BC, these megaliths are arranged in long lines, circles, and other formations. They are thought to have held religious or ceremonial significance, though their exact purpose remains unclear. The stones vary in size, with some standing several meters tall, and are made primarily of local granite. The site is one of the largest and most impressive collections of megalithic monuments in the world, attracting researchers and tourists alike.
