An early 20th century water tower is located within the grounds of St John's Hospital. The structure is believed to have been built in about 1924, and combines a remarkable slenderness with elegance of form. The tower is 125ft high overall, and supports a hexagonal tank of 30,000 gallons capacity on top of six slightly splayed legs. It stands upon a shallow raft foundation of reinforced concrete, and was originally built to serve the hospital laundry. {1}{2}{3} The tower was specifically mentioned in the listing documentation for the main building at St John’s Hospital (PRN 61564), but was demolished in July 2014. {4}{5}
