St Ann's Head
Lighthouses have existed at St Ann’s Head since 1713. The present structures, the old high light and the low light were built respectively in 1800 and 1844.
Just before WW2, the redundant high lighthouse of 1800 was crowned with a concrete observation box to become the Milford Haven Fire Command Headquarters. The site also acted as the Royal Navy’s Port War Signal Station (PWSS), identifying any warships approaching the entrance to the Haven.
During the First World War the site had functioned in a similar role, but the observation post used at that time has been demolished. However traces of the First World War do remain in the form of rifle loopholes cut into the boundary wall that divides the Trinity House land from the rest of the peninsula. During the Second World War the approach to the wall from the north was further protected by barbed wire entanglements and a minefield running the width of the headland.
