The Rat Tunnel - Bollington

Came across this some time ago, when walking past with the doggo i noticed the inviting culvert entrance and pinned it on my maps for a future visit. Maps doesn't give anything away really with this one and it's one you’d only know about if you were local. The culvert bends round to the left for a few hundred yards with a sewer line present throughout. Further upstream are a couple of shorter culverts and some bridges before you reach a former mill. A great example of Victorian era engineering that is still working and in use today without us necessarily realizing so.

History
