Vestiges that reach far back into history.The most important Megalithic site on the peninsula is without a doubt the Kerbourgnec Alignments situated in Saint-Pierre-Quiberon. It is made up of a total of 25 sometimes oddly-shaped menhirs aligned in a sequence of five rows. Only a little further from this site, there is a "Cromlec'h" with a total of 27 menhirs placed in a circle - it is the third largest in the whole of Morbihan.
