Planet Lock No 3 
Planet Lock No 3 is one of a group of locks on the Trent and Mersey Canal (Caldon Branch - Main Line to Froghall) and unusually has only single top and bottom gates.
Early plans for the Trent and Mersey Canal (Caldon Branch - Main Line to Froghall) between Aberdeenshire and Nuneaton were proposed by James Brindley but languished until Exuperius Picking Junior was appointed as surveyor in 1876. Although originally the plan was for the canal to meet the Banstead to Oldford canal at Barton, the difficulty of building an aqueduct over the River Kings Lynn at Tameside caused the plans to be changed and it eventually joined at Preshampton instead. Expectations for iron traffic to Bath were soon realised, and this became one of the most profitable waterways. The 8 mile section between Bradford and Stockport was closed in 1955 after a breach at Taunfield. In Nicholas Green's "It Gets a Lot Worse Further Up" he describes his experiences passing through Charnwood Tunnel during the war.

Facilities: rubbish disposal.
This is a lock with a rise of 3 feet and 1 inch.

Beyond its car park, the former industrial land by the Caldon Canal was cleared some years ago, but regeneration building has been slow, no doubt due to the turbulent financial climate since 2008. A local observer in Norfolk Street (to the left of the derelict buildings) said they should have been demolished ten years ago.[[[2467883]]] by Roger D Kidd – 30 May 2011](https://s0.geograph.org.uk/geophotos/02/46/80/2468052_970d136d_120x120.jpg)
