Roadside Water Trough – West Jesmond, Newcastle Upon Tyne

A roadside water trough, located in Forsyth Road, West Jesmond, Newcastle Upon Tyne,  a few yards from the junction with the Great North Road.

An Ordnance Survey bench mark – a horizontal line with an arrow pointing up from below – is carved into one end of the trough.

These marks were cut by Ordnance Survey levelling staff to provide a network of points at which height has been precisely measured (to the centre of the horizontal line) above sea level.

There used to be about half a million bench marks in Great Britain but they are not needed any more, due to satellite technology,  and about half have disappeared.
