Dolmen of Praz Berthoud
The Dolmen of Praz Berthoud, reconstructed in 2010, is located above Onnens , near Yverdon-les-Bains , in the canton of Vaud in Switzerland .
The remains of around 2300 BC Dolmens from Praz Berthoud, built in 2000 BC, were uncovered by a bulldozer during the construction of the A5 motorway between Yverdon and Neuchâtel NE . It is the first megalithic complex to be discovered in the canton of Vaud .
The dolmen consists of large slabs and blocks. Not all of the blocks that originally made up the memorial were found. Of the eight thick rocks that make up the replica dolmen, five are the original stones, while the rest are replicas. The dolmen is now 40 meters from the site of discovery.
During the excavations, the researchers came across arrowheads and post holes. This suggests that there was a building near the dolmen.
