This earth mound feature is all that the public can see of an ice house structure that served the Kearsney Manor House. Ice Houses were built before the invention of the refrigerator to keep food fresh for longer. They were often filled with ice during the winter months but this structure also benefits from an underground stream adjacent that kept the room cool throughout the year.
Victorian Ice House - Ice houses were introduced to Britain around 1600 but only richer houses had ice houses built. British ice houses were commonly brick lined, domed structures with most of their volume underground.
