The construction
of the Centre Bastion
Battery began in 1825 to fill in the gaps between the old indented
lines and the new indented lines. The Bastion was first equipped
with an extensive range of 64 pdr SB guns then later two 10" mark 111
RML's were installed. In 1899 a three pdr QF practice battery was
placed between the two ten inch batteries. In 1901 a new battery of
4.7" QF guns was constructed centrally between the 10" emplacements.
There were no guns placed on the battery during World War Two as their
role was replaced by twin 6 pdr guns at Garrison Point.
The square tower
was provided with a false pitched roof and fake windows to camouflage
it to look like a domestic building.
