Stop 7: (330 m) The navigation tower
This navigation tower was built in 1970, and is over 58 metres high. The deep-water channel into
Milford Haven is very narrow, so tankers, ferries and other large vessels have to be sure of their approach to the
Haven. From the open sea, they follow a north-easterly route at first, followed by a dog-leg change of direction to
the east. There is another set of three navigation towers with lights at West Blockhouse Point (Stop 10 on your

correct angle of approach to the Haven.

the sea on the landward side, and the gun parapet facing out to sea. The parapet is surrounded by 1.4 metre-thick
walls of limestone, capped with granite.
