Castletimon Ogham Stone lies prone by the roadside 2.2 km (1.4 mi) west of Ballynacarrig beach, which opens onto Brittas Bay. Potter's River flows 260 m (280 yd) to the south.^[2]

Castletimon Ogham Stone was carved c. AD 350–550, and was rediscovered in 1854.^{[citation needed]}

Local legend claims that the Ogham stone was once picked up by the Castletimon Giant and thrown down the hill; the scratches on it were left by his finger nails. Another says that a local man took the Ogham stone to use as a hob stone. The Aos Sí (fairies) got angry and made his cutlery dance and jiggle. After a week of this he returned the stone to its place.^[3]
