This is the only one of Bath’s Georgian pleasure gardens to survive. When it opened in 1795 it was privately run and visitors paid an entrance fee. Now it is a public park with a hidden surprise. There are all the expected tree-lined walks and colourful flowerbeds. But you don’t expect a railway. The Great Western line was cut through the gardens around 1840. To avoid spoiling the amenities, it lies in a deep cut, so that the trains are invisible except from attractive bridges.
