Description: Ambervale was originally known as Prospect House, it existed at least as early as Ashover Hydro, since both are listed in Harrod's Directory for 1870. Ashover House Hydro was built in 1869 to try to turn the village into a somewhat exclusive watering place for both short and long term visitors. The success of the industry was comparatively short lived and did not last until the end of the century.
