Pool of London [SEP] Introduction
The Pool of London is a stretch of the River Thames from London Bridge to below Limehouse. Part of the Tideway of the Thames, the Pool was navigable by tall-masted vessels bringing coastal and later overseas goods—the wharves there were the original part of the Port of London. The Pool of London is divided into two parts, the Upper Pool and Lower Pool. The Upper Pool consists of the section between London Bridge and the Cherry Garden Pier in Bermondsey. The Lower Pool runs from the Cherry Garden Pier to Limekiln Creek.
