Barclodiad y Gawres (Welsh for 'The Giantess's Apronful'; Welsh pronunciation: [barkˌlɔdjad ə ˈgau̯rɛs]) is a Neolithic burial chamber between Rhosneigr and Aberffraw on the south-western coast of the island of Anglesey in North Wales.[1] It is an example of a cruciform passage grave, a notable feature being its decorated stones. Similar graves and marks exist across the Irish Sea in the Boyne Valley.[2]
