This is the northern portal of the iconic Trent & Mersey Canal tunnel. The tunnel keeper has put the barrier down indicating that boaters should not enter until they are given permission to do so. This is essential because boats cannot pass inside the tunnel and at the time a convoy of four boats was making its way northwards. In places headroom is restricted so boats must be able to pass under the bar suspended from the tunnel mouth.
