Otherwise known as East Old Law, this is one of a pair of navigation beacons on Guile Point. Built in the first part of the 19th Century by Trinity House of Newcastle upon Tyne, their purpose was to guide sailors into Holy Island Harbour by aligning the two beacons. By the 1990s, a solar powered light had been fitted to Guile Point East, as seen in this photo and Guile Point West (or West Old Law), just visible in the background to the right of Guile Point East, became redundant. Responsibility for Guile Point East was transferred to Trinity House (as distinct from Trinity House of Newcastle upon Tyne) in 1995.
In the background is the Lindisfarne Oysters building, who farm Pacific Oysters in the waters here, with Guile Point West just visible to the right of Guile Point East.
The two beacons are grade II listed - see
