Brittany is very like rural Cornwall and Wales: it’s the place names as much as the landscapes. Breton, Cornish and Welsh (I’m told) are all Brythonic/P-Celtic languages – Irish, Manx and Scottish Gaelic are Q -Celtic. The Breton anthem,Bro Gozh Ma Zadoù, is sung to the tune of the Welsh anthem, Hen Wlad Fy Nhadau.
