Gunpowder magazine

A gunpowder magazine, also known as a polverista, is a magazine (building) designed to store the explosive gunpowder in wooden barrels for safety. Gunpowder, until superseded, was a universal explosive used in the military and for civil engineering: both applications required storage magazines. Most magazines were purely functional and tended to be in remote and secure locations.

There are surviving Magazines at the following locations, among others:

There are magazines at:

The Ballincollig gunpowder mills were first opened in the late 18th century and were bought, in 1804, by the United Kingdom of Great Britain and Ireland's Board of Ordnance to help defend the Kingdom against attack. They were one of three royal gunpowder factories; but the Ballincollig mills became disused after the end of the Napoleonic Wars. They were sold off by the government in 1832, in a semi-derelict condition; but were bought by a Liverpool merchant and were reopened to manufacture gunpowder; finally closing, just over a century ago, in 1903. Many buildings survive and, together with the associated canals, were incorporated into a regional park - Ballincollig Regional Park. The site contains a number of powder magazines, as well as Expense magazines.

The No. 2 magazine was built by the Board of Ordnance and is the oldest magazine. It is 29 foot (8.9 m) long by 28 foot (8.6 m) wide. It has a groin-vaulted roof. The magazine is protected by earthen banks on two sides; with doors at both ends. The No. 1 magazine is newer; and was built sometime after 1828. It is 80 foot (24.5 m) long by 25 foot (7.6 m) wide and has solid walls, but is now roofless.

There is a surviving Magazine at Camden Fort Meagher, part of the defences of Cork Harbour.

Rocky Island, midway between the mainland and Haulbowline Island (which at the time was an ordnance depot), is dominated by a magazine complex dating from 1808; it held up to 25,000 barrels, and was the principal store for the whole of Ireland. In 2007 it was restored and converted into Ireland's first crematorium outside Dublin.
