Just to confirm it is the white undressed stone standing some 10m north of the old windmill. Not sure what the standing stone next to the ruined building is, but it is typical of the Anglesey stones being broad and thin. If you are inclined to climb over the fence behind the building is a narrow track/green lane which leads to a field perhaps 30m away. At the end is another “standing stone” forming the gatepost. 6/9/06
