Mané Roularde is just at the back of St Trinité sur Mer – the posh, moneyed end of Carnac town where people express their wealth with glamorous marine craft.
Mané Roularde’s particular feature is that it is a very VERY long allée couverte, perhaps 15 or 20 metres but only four or five feet across down its whole length.
Sadly most of its caps are gone, but I’d now seen enough allée couvertes to imagine what it was like.
