St Anns Head Lighthouse

Milford Haven has long been recognised by merchants and shipowners as one of Britain’s finest deep water harbours – it was from here that Henry II led his army into Ireland in 1172. Now large fleets of trawlers and oil tankers gather in the anchorage. At the approach to this famous port lie dangerous reefs just below the surface, almost in mid channel and in two groups through which shipping must pass.

One of the greatest dangers lies some 7 miles south-east of St. Ann’s Head, this being the dreaded Crow Rock and Toes lying off Linney Head which have claimed many more vessels than the reefs within the harbour. Today, two usable channels are marked clearly by sets of leading lights, all vital to safe navigation.
