A hydraulic accumulator tower is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure that is applied by an external source. The external source can be a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. This one is located some distance away from the current Poplar Dock, and separated from it by the Trafalgar Way access road to Canary Wharf and by the Boardwalk Place residential estate, but in the 1870s when it was built an arm of the dock extended where the modern day developments are. When it was built the whole area behind and in front of it would have been covered by the dock railway system. This one is now a Grade II Listed structure. Billingsgate Market is beyond.
