 In 1882 the work stopped for a re-think and once again restarted in 1886 when the decision was taken to delete from the plan one quarter of the design.This meant the loss of the Main Magazine (which was to have been in the western corner) and one quarter of this structure survived, much modified to become the above ground water tank.The well was also removed from the plan so the water main had to be laid from Fort Horsted and the proposed under-bridge caponier was never even started.
