A short walk from Coalport China Museum, alongside the Shropshire Canal, takes you to the Tar Tunnel.
Over 200 years ago natural bitumen trickled like treacle into pools. It was turned into pitch, lamp black and rheumatics remedies. Now you can walk along this brick-lined tunnel where the bitumen still oozes through the walls. Don't forget to pick up your hard hat on the way in.
