This photograph, taken about 1980, shows the then surviving buildings of the gasworks which George Bower of St Neots advertised as having built in the 1850s for the Melville family at Branston Hall.
It was later extended, possibly by Porter & Co of Lincoln, and ceased working in the 1920s.
The small building with the ventilators is the retort house; the condenser and purifier stood outside and coal was stored in the building on the left.
Today only the former threshing barn at the rear survives (as a house) together with the pit of one gasholder.
