Monuments

A bombing range is an area of land and its associated buildings and targets that was used to practise dropping bombs, during the First and particularly Second World Wars. A range marker allows the pilots to locate the bombing range or the target that they are aiming for in training.

Markers are designed to be distinct. Often they are 25m long, arrow shaped, constructed of hardcore or concrete, and would probably have been painted white. They can also be concentric circle targets. 

They may be associated with other military structures like an observation tower or control tower but aerial training sites wouldn’t have needed much ground infrastructure.
