Description

The flint-walled garden tunnel at Ingress Abbey is a garden feature built in the early to mid 19th century, with alterations made in the 1940s. The tunnel has flint walls topped with garden bond brickwork and a brick round-headed ceiling, measuring approximately 75 to 100 feet in length. It was originally part of a garden walk that connected different areas of the grounds, allowing views of various garden features as it passed through a large chalk outcrop. During the Second World War, the tunnel was blocked off at the western end, and a concrete blast guard was added at the eastern end to serve as an air raid shelter.
