The so-called “Dolmen” is a megalithic stone formation, some 6,000 years old. It stands near the city centre, but hundreds or thousands of years ago, this used to be the bank of the Loire Estuary. Next to the dolmen with its 2 metre-high vertical stones and its horizontal stone weighing 7 tons, there is a 4-metre high “menhir”, or standing stone. The monument is freely accessible.
