Description

The dam and cascade at Gilston Park, located 500 metres southeast of the house, were remodeled around 1851 by P C Hardwick for John Hodgson Esq. This structure is part of an early 19th-century ornamental lake within the park. The overflow in the center takes the form of a naturalistic waterfall cascading over a high cliff made of artificial stone, which is similar to the grotto added in 1887 by A W Blomfield for E S Bowlby Esq. The dam was later adapted to drive an electric turbine around 1902, with the foundations of the turbine located to the south of the cascade. This site is recognized as an important historic garden feature and represents an early use of artificial stonework, as well as a notable technological adaptation for generating electricity.
