Execution Dock was a grisly place in the River Thames near the shoreline at Wapping, London, that was used for more than 400 years to execute pirates, smugglers and mutineers who had been sentenced to death by Admiralty courts. The "dock" consisted of a scaffold for hanging. Its last executions were in 1830.
