The Heugh Hill Light is a metal framework tower with a black triangular day mark, situated on Heugh Hill (a ridge on the south edge of Lindisfarne). Prior to its installation, a wooden beacon with a triangle topmark had stood on the centre of Heugh Hill for many decades.[3] Nearby is a former coastguard station, recently refurbished and opened to the public as a viewing platform. An adjacent ruin is known as the Lantern Chapel; its origin is unknown, but the name may indicate an earlier navigation light on this site.[citation needed]
