The line of trees and bushes across the meadows at the centre of the photograph is the line of the Rosehall canal. It is, according to the local history group, the most northerly canal in Britain. It was initially used to bring in materials for renovation work on the Hall. Disused for many years, it is now not really recognisable as a canal, being more of a wide ditch now. The basin was expanded into an ornamental lake. It may not be the officially most northerly canal because it was built on private land by the landowner and no Act of Parliament was needed or granted, as with the rest of the British canal network.
