Currently locked, Clarendon Arch is the oldest surviving structure on the New River. The information board reads "The Arch, which can be viewed from the bottom of the steps, is the upstream end of a barrel vaulted tunnel which carries the Salmons Brook below Bush Hill. The Brook's source is near Hadley Wood on the Hertfordshire boundary from where it flows eastwards below the New River, on the opposite side of Bush Hill, and finally meets the River Lea at Edmonton. Built in 1682, the arch was named after the then Governor of the New River Company, the Earl of Clarendon. This work is commemorated by the carved ornamental keystone, with the inscription 'This arch was rebuilt in the yeare 1682, Honourable {Henry} Earle of Clarendon being Gov.'.  The arch was again rebuilt in 1725 and is now a statutory listed Grade II structure.

Still not sure where this is but assume it’s ok to say it’s historic.....& invisible

Not accessible. The arch is hidden behind a locked gate and 'Private Property' signage. I had to zoom in on a picture I had taken of the explanatory sign just to be able to read it. Quite a shame.

Currently closed access to view the arch which meets the new river. Nice view over and in between lovely gardens on the hill, looking down into salmons brook. The council should really open it up, but sadly like so many places, I guess can be vandalized. Easy to miss this if it were not for the sign.

Better class of wildlife at Clarendon Arch, Bush Hill... Mandarin Ducks?!

There is currently no access to the arch and the information board, which is a real shame for an important part of Enfield's history and heritage. This is one of the sights on the New River walk.

The whole area is unmaintained. Trash on the ground, and pathway is unceremoniously fenced off with ugly "private property" signs. Shameful.

Area is now locked away and out of view. Shame
