Slightly related (and a bit of ATC history - perhaps)
Many years ago Deancross VOR (DCS) was moved from it's original ,location. I suspect this was to move flights away from Sellafield.
It was relocated approx 8nm NNE into 2 tempoary caravans before it was established at it's present location 9.5 nm from the original site
The original equipment building still exists and is used as a store building for an motocross track!
As regards towers I'm sure I was told that the new tower at Newquay is a temporary structure
