There's a sizeable cluster north of London on there - trying to work out why, I suspect it may be the proximity to Bedford Aerodrome and the fact that it's a very farming centered area and aerial photos can be very useful to farmers.

Historic England is the organisation name, so the title should probably be

Historic England Aerial Photo Explorer.

Amazing! Makes me a bit sad to see all those beautiful buildings destroyed to make way for skyscrapers and bland office buildings...
