It's the near-forgotten tunnel that's only really known by Edinburgh locals who are able-bodied enough to scramble underneath it.
Situated beneath the Union Canal between Lanark Road and Redhall Park is an eerie passageway that almost looks as if it was built for Hobbits.
Muddy and partially hidden by foliage, the towpath tunnel is virtually unknown to most of the walkers in the area, who generally opt for the modern concrete footbridge that traverses both Lanark Road and the canal.
