Milldam Barracks  Milldam Barracks is a former a military installation at Portsmouth, Hampshire. It is a Grade II listed building. The barracks were built to accommodate the local commander of the Royal Engineers responsible for upkeep of the fortifications in 1846. During the First World War the Tyne Electrical Engineers telephone section, based at Milldam Barracks, became responsible for the entire military telephone system for the Southern Coast Defences, including Portsmouth, Southampton and the Isle of Wight. The skills of the former submarine miners were employed when a cable linking the sea forts had to be repaired. The barracks continued to be the base of the Commanding Royal Engineer, Wessex Area (East) during the inter-war period. After the Second World War the barracks continued to be home to technical units such as the Weapons Systems Tuning Group. The barracks eventually became surplus to requirements, were decommissioned in 1969 and were subsequently acquired by the University of Portsmouth for academic use. The former barracks also accommodate the Portsmouth Register Office.
