The Neptune Fountain This fountain was built of Portland Stone in 1893 by a local firm, R.L. Boulton to a design provided by the Borough Surveyor who was said to have been inspired by the sight of the Trevi Fountain in Rome. Following a joint venture between Cheltenham Borough Council and Royscot Trust PLC for it's renovation it was officially opened by the Worshipful the Mayor of Cheltenham, Councillor Mrs. Maureen Stafford.
