Summerhouse And Sluices At West End Of Island, 240 Metres South-East Of Abbey

The summerhouse and sluices, located at the west end of the island, 240 meters southeast of the Abbey, were built around 1813 for Thomas or James Henry Leigh, based on a design by Humphry Repton. The structure has been repaired in the late 20th and early 21st centuries. It features ashlar walling that supports a walkway, which is slightly convex on the upstream side. There is a central round-arched opening that allows water to flow freely. To the left of this opening, there is a plain opening with the remains of double wooden sluices fitted with iron components. Above the central opening, the wooden summerhouse is designed in a Classical style, characterized by fluted pilasters, a pedimented gable, and arch-braced openings on three sides that create the appearance of round arches. Surrounding the summerhouse are wooden diamond-lattice railings. Inside, the summerhouse contains a wooden bench and has a floor made of pebbles arranged in diamond patterns.
