Built in 1860 to store the gunpowder used in the local gold
mining, the powder magazine was designed to minimise the risk
of explosion. Only copper fittings were used and an elaborate
lightening rod was fitted. People entering had to wear special
shoes. Should an explosion occur the design of the building and
compound would ensure the blast traveled upwards. The magazine
closed in 1918 and fell into decay. The roof was removed to stop
vagrants sleeping there and was almost demolished. The National
Trust restored the building in 1966.
