The alignments at CARNAC – rows of 2000 or so menhirs, or standing stones, stretching for over 4km to the north of the village – constitute the most important prehistoric site in Europe, long predating Knossos, the Pyramids, Stonehenge or the great Egyptian temples of the same name at Karnak. Mercifully, they now stand a few kilometres in from the sea, meaning you can combine a reasonably tranquil visit to the stones with a stay in the popular, modern seaside resort, pretty hectic by Brittany's mild standards.
