WWII sites in Cornwall UK ?

Hi,

I've just moved from Northamptonshire UK where there a number of WWII airfields which I loved walking around and researching. Now I'm in Cornwall I wondered if any of you chaps knew of any interesting sites down here?

Thankyou,

The Defence of Britain Project database is now online so you could start there

The RSG site is primarily Cold War but many of the sites date back to WWII

St.Eval was a particularly important Coastal Command station for submarine patrol. It may also have been the station where P.M.S. Blackett and others set up their centralized maintenance system (which increased hours flown without increasing workload.)

Culdrose/Helston (RCN station) was where Barnes Wallis did his postwar research on the Swallow tailless aircraft (see Morpurgo's biography).
