Description The Low Light was constructed a few hundred yards from the main light in 1843 to provide (with the main lighthouse) a pair of lights which would become aligned to help ships avoid the North Carr Rock seven miles to the North of the island. It was first used in April 1844, but is no longer used, having been made redundant by the establishment of the North Carr Lightship in 1887 and the building is now used for bird watching.
