Hanbury Hall was built around 1701 and was built for the wealthy lawyer Thomas Vernon. Extensive formal gardens and parkland surround the property. In the 19th century a tunnel was built to allow servants to cross one of the carrageways remaining hidden from view. It is locally known as Snobs' Tunnel, reflecting the sensitivities of those who built it rather than its users.
The tunnel is around 20 metres long and the passage beneath around two metres wide with an arched roof a little less than two metres at maximum height. It is constructed out of brick, with some sandstone used in the approach walls.
Today Hanbury Hall is a National Trust property and the tunnel can be seen and used during opening hours, running between an orchard and a formal pool. It is listed by Historic England ar Grade II along with the adjacent retaining wall.
