Neptune Fountain

This fountain in Cheltenham was designed by Joseph Hall, and constructed by R.L. Boulton and Sons in 1892-3 but they were into "Sustainability" way before it became fashionable. Instead of connecting it to the water mains, they built it directly above the culvert that carries the mighty River Chelt under the centre of the town. There's a pump to bring the water up and keep old Neptune cool.

Those with a passing knowledge of the town might think I'm joking about the "mighty" River Chelt. Sure, it's only a thin blue line on the map and often  masquerades as a pleasant stream but give it some decent rain and that culvert just isn't big enough...
