Duke of Northumberland's River
This section was built during the reign of Henry VIII by John Gates after the dissolution of the Monastery at Syon. It was to augment the water supply to mills and allow new ones to be built, thus providing a source of revenue for the Duke of Northumberland. It takes water from the Colne and flows through this stretch alongside the Longford River. Both have been diverted in association with the construction of Terminal Five but skirts the western and southern perimeter of the airport.
The waterway was constructed in 1638 at the instigation of Charles I in order to increase the water supply to Hampton Court and allow water features to be developed. It had a variety of names - the New River, the King's River, the Queen's River, the Cardinal's River, the Hampton Court Cut, and the Hampton Court Canal. In this section it runs parallel with the Duke of Northumberland’s River.
