View over Stack Rock Fort to Angle Penninsula and Thorn Island.
Perhaps the most striking of all the Haven forts , sitting remote on a mid-channel rock
in the haven .
Originally a Cambridge Gun Tower built 1851 , similar to the Martello Towers
of Pembroke Dock .
Between 1859 and 1870 the present building was built , a circular casemated fort with
23 guns which completely enveloped the former tower .
Accommodation for 180 men .
