Remains Of Sluice Gate At West End Of The Cut

The remains of a sluice gate are located at the west end of the cut in Seaton Sluice. This structure, likely from the 19th century, replaces an original sluice gate built in 1764 by engineer Thomas Delaval for John Hussey Delaval. The remains include a heavy boarded gate that slides within U-section girder uprights, which are set into rock. This landward gate is part of the 'new cut' constructed between 1761 and 1764, designed to create an all-weather harbour entrance and a deep-water dock. This ambitious engineering project, which cost £10,000 and involved lime blasting, resulted in the first floating harbour on the east coast. The sluice gate is listed for its historical significance.
