RAF Wroughton is south of Swindon on the A4361 or you can take the B4005 from Chiselden. There are several ways to view it the map will show you where to go.
OS Ref: SU143788
You can use the Ordnance Survey 'Get a Map' and follow the instructions. Copy and paste the map reference. This reference is the Control Tower.
I have now split RAF Wroughton into 10 sites and will gradually updating them, so for now not all will be working.
