Clarendon Arch And Tunnel

Clarendon Arch and Tunnel is a Grade II listed structure located in Bush Hill, N21. The arch features an inscription that reads, "This arch was rebuilt in the year 1682. Honerable Henry Earle of Clarendon Being Gov." The long tunnel, which is barrel vaulted and constructed mostly of pinky-yellow stock brick, likely dates from the early 19th century. At one end, the arch ring is made of Portland stone and includes the aforementioned inscription along with a fine shield of arms, complete with mantling, helm, and crest of Myddelton. The structure is capped with a plain parapet.

The tunnel carries the Salmons Brook beneath the New River. On the northwest side of the tunnel, there is a stone with an inscription stating: "This bank of earth was raised and formed to support the Channel of the New River. And the frame of timber and lead which served that purpose 173 years was removed and taken away. MDCCLXXXVI Peter Holford Esquire, Governor." This work is part of the New River project, which was established in 1613 by Sir Hugh Myddelton to provide a cleaner water supply to London.
