Pembroke Docks

South West Gun Tower. Constructed in 1848 as part of the defences of Portland Dock. During WW2 the tower was fitted with four .303 Lewis Machine guns to provide Anti-Aircraft cover and train the RAF Sunderland Flying Boat gunners.

In 1940 it opened fire on a German bomber and became the only fortress on the Haven to fire in anger.

Much of the former area of the Flying Boat Station at Pembroke Dock is now utilised by the ferry terminius. The two C-type hangars and the T2 hangar have been demolished , but the slipway up which the flying boats were hauled is still in-situ. However, sources appear to differ as to what actually remains. Pre-1960s OS maps seem to have the building layout redacted

	This is near as I could to the hanger. Theres an excellent museum round the corner with information on the building of the Flying boats and the docks in general.
There's some lovely Victorian buildings in the docks area.
