Green Park station was opened in 1870 as the terminus of Midland Railway's Mangotsfield and Bath Branch Line.

It was built in an elegant style which blends well with the Georgian buildings around it and includes a vaulted glass roof in a single-span wrought iron arch structure.

From the late 1840s the design was adapted in Britain for construction in wrought iron, and the Avon Bridge is a fine surviving example.

Since closure of the railway, the bridge has been adapted to provide vehicular and pedestrian access to Sainsbury's supermarket.

Through trains had to reverse at Bath, and the most famous of these was the named Pines Express from Manchester (and at times other northern originating points) to Bournemouth West.

Parts of the distinctive glass roof were damaged during bombing raids in April 1942, and the glazing was not re-instated during railway usage after the war[citation needed].

A Grade II listed building,[7] Green Park Station has become an active retail and events space.

Since the early months of 2021, significant parts of the station have been cordoned off to allow restorative works to take place on the roof.

During and before these works took place, large glass panels came loose from the main structure, falling to the floor below.
