At the junction of Albert Embankment and Black Prince Road are the remains of White Hart Dock. This dock was used by Doulton's to bring clay and other materials up the river and transport finished goods (e.g. stoneware conduits, drainage pipes, electrical, plumbing and sanitaryware goods) to the Port of London for forwarding through out the world. After the Albert Embankment was built the barges would be moored up till the tide was just right when the bargemen would move them through short tunnels under the roadway to the dock. The arched river entrances to the two tunnels are currently hidden by the floating restaurant
All that remains of the dock are two modern flood gates which give access to a sloping slipway that is surrounded a brick wall about 5 feet high. The brick walls have been reinforced with some modern steel bracing over the tunnel entrances to the Thames which still exist so the water level in the dock rises and falls with the tide.
During the Second World War the dock was used as an Emergency Water Supply and the painted initials EWS can still be made out on the walls. Presumably the tunnels had some form of dam that let water enter the dock at high tide but retained it when the river level fell. The dock then acted as a sort of huge water tank that was replenished every high tide. The location of the dock right next to the London Fire Bridages Headquarters must have made it an ideal location for such a supply.
