Rae in addition if you have any interest in WW1 memorabilia, then at the airfield at St Omer there is a memorial near to the entrance from the road and, if the club hanger is open, there are quite a few artefacts within it from the period. The airfield is around three miles from the town.
St Omer was the principal staging post for newly trained pilots and replacement aircraft on their way to the Front from England, in WW1.
