In the late 1970's/early 1980's my dad worked for the Department of the Environment, which at the time was responsible for the maintenance and construction of all Government-owned buildings, including in Medway, the likes of Crown House in Chatham (now the Jobcentre), Rochester and Upnor Castles and all the buildings in the Dockyard, HMS Pembroke and the various Army barracks in the area. He told me a tale of how the construction of a tunnel from Chatham Police Station to the then new Magistrates Court next door had to be abandoned because the builders were constantly fighting a losing battle against flooding in the tunnel.
