The Old Lighthouse at the Point of Ayre was the work of Robert Stephenson and was built on the northern-most tip of the Isle of Man. It was first lit in 1818 and had Argand lamps with two foot reflectors.  Its foghorn house and a subsidiary light, which was made necessary by the accretion of shingle banks, were built 230 metres to the northeast in 1899 and lie between the Old Lighthouse and the present tideline.  The original lighthouse is shown on the 1870 1:2500 scale Ordnance Survey map.  It remains operational to the present day, though is now fully automated.
