Listing Text: 686-1/0/10009 MEDWAY ROAD 28-FEB-08 GROUP OF ANTI-TANK PIMPLES GV II Anti-tank obstacles of pimple form, circa 1940 DESCRIPTION: Concrete anti-tank pimples (truncated pyramids also colloquially known as 'Dragon's Teeth'). Forming a south-west to north-east line approximately 85m in length along the northern side of Medway Road, to the east of Cumberland Road and to the south-east of the Chatham Lines. The pimples are five deep in places and are of the standard symmetrical form. Some, in the central part of the line, are part buried and it is assumed, given the topography, that further examples survive but are fully buried to the east. In the west of the line the anti-tank pimples are visible, although overgrown, and are a good surviving group. HISTORY: These anti-tank obstacles were erected circa 1940 as part of the anti-invasion defences for Chatham, Gillingham and Brompton in defence of the dockyard and barracks. This line fills a gap in the existing Napoleonic defences which were adapted to form an anti-tank stop-line during the Second World War. Specifically these obstacles bridge the gap between a row of former dockyard police houses and the defended entrance to the Nore Command Bunker. (The bunker was for the Commander-in-Chief who had responsibility for protecting the entrance to the Port of London as well as traffic up and down the east coast.) The anti-tank obstacles are documented in `The Garrison Plan to Defeat Invasion' of 1941. Tactically their purpose was to prevent enemy progress but in the event that an enemy vehicle did attempt to drive across an obstacle, its vulnerable underside would be exposed to defensive fire. CONTEXT: Anti-invasion defences have been the subject of an English Heritage Monument Protection Programme (MPP) study which looked at the known resource, drawing on the Council for British Archaeology's Defence of Britain project, and made recommendations for designation. The MPP study considerably enhanced the understanding of the resource and identified 112 examples of sites with anti-tank pimples nationally, of which 46 were considered to be good examples.

They have group value with The Lines and the adjacent Nore Command Bunker.
