Many airfields from the period still exist in some form today.
Take a look at a modern satellite image and you will still see runways, hard stands, munition bunkers and control towers and rotting Nissan huts on many ww2 fields.
my closest field is here:

It still has plenty of features, including the tower. It is far from unique.
