Castle Carr Water Garden And Pumphouse

An ornamental water garden, completed in 1870, is situated between two reservoirs. It was designed by James Hogg of Halifax and built by the Halifax Water Corporation for Mr J P Edwards, whose Castle Carr estate the garden occupies. The garden was constructed as compensation for using Edwards' land during the damming of the Luddenden Valley, intended to provide additional water for the expanding city of Halifax.

The garden's main feature is a large circular pool with a central jet fountain, originally reputed to have risen to a height of 100 feet, possibly the second-highest in England. Water flows into this pool via a stepped cascade from the north, approached by flanking staircases. Above the cascade is a double arched tunnel/bridge, featuring plain ashlar parapets. Four smaller circular pools, each with a single jet fountain, are located to the north west, north east, south west, and south east of the main pool.

Further along the north west edge of the garden is another small circular pool and an octagonal pumphouse. This pumphouse is constructed of rock-faced stone and has a chamfered plinth, bracketed cornice and chamfered parapet. The entrance front features double plank doors, chamfered jambs, and an inscribed lintel and gable reading "1870 HALIFAX CORPORATION, LUDDENDEN VALLEY EXTENSIONS". The side fronts have single blocked windows. A smaller, lower circular pool is located within the southern end of the main pool, featuring curved waterfalls. A viewing platform is situated at the north edge of this smaller pool, accessed by three stone flying staircases linked by small curved bridges within the lower pool. These form a central island with four cut-water buttresses projecting above the parapet wall. South of this pool, a long, narrow canal discharges its water down another cascade at its southern end into the lower reservoir. All stone abutment walls are of rock-faced ashlar, with chamfered ashlar parapets.
