Modern beacon.


The beacon stands at the end of the outer breakwater protecting the mouth of Castletown harbour. The structure is a masonry cylinder built in regular, course limestone blockwork,with an ogee-profiled roof.


The beacon is painted white with a red band just below the light. A inscription 'VR 1849' in contained within a shield-shaped outline.


The beacon marks the end of a breakwater, the original part of which was completed in 1845 at a cost of £2,700. Its construction created the New Basin, sometimes known as the 'dry harbour'. The basin was criticised in an official report in 1845 as 'unnecessary'.


The breakwater was extended by 30 yards in 1849, at which point the beacon was completed.
