One of a pair of disused lighthouses at the mouth of The Nene (this being the easterly one), built as part of a scheme of river improvements in 1826-30. The structures resemble tower mills due to their tapering sides and octagonal tops. This structure has an upper circular window and a central octagonal chimney. The Nene Outfall Amendment Act of 1829 authorised the Commissioners to erect lighthouses or beacons without the sanction of Trinity House. These lighthouses were more landmarks rather than lighthouses in the usual sense. For the full description and the legal address of this listed building please refer to the appropriate List of Buildings of Special Architectural or Historic Interest. {1}{2}{3}{4}
