It is situated on the north side of the town, north of Oakengates.
It was once the site of a inclined plane connecting the now-abandoned Shrewsbury Canal and a smaller canal, the Wombridge Canal, 75 feet higher in elevation and part of the east Shropshire canal network. The Trench Inclined Plane ceased operations in 1921 having been built in 1793.
It was the last working canal inclined plane in the United Kingdom.
