The Magazine is constructed of London stock bricks withThe southern side of the magazine covered by a large earthen bank in order to protect the explosives from potential gunfire from warships, it was originally designed to contain 320 barrels of explosives. The earliest depiction of the magazine is in an early-19th century plan of the castle which clearly shows the original rectangular form surrounded by earth banking. Summarised from sources (1-2)
