The Martello Tower, Powder Magazine and Gun Battery in 1868.
Three of the four 32-pounder guns mounted "en barbette" on traversing
carriages can be seen on either side of the Tower with the three 18-pounders
in a row on the left. The 9-pounder can just be seen over the extreme left
end of the Magazine building, in front of the ruins of the emplacement for
the mortars.
The Martello Tower was used as a navigational beacon for ships entering
Simon's Bay and was consequently white-washed in about 1843.
