Many cities in the UK are surrounded by acres of protected land that form Greenbelts. They are what makes my house feel almost like it’s in the countryside, although it’s actually only 15 miles as the crow flies from the bustle of Trafalgar Square.
Greenbelts are the result of policies created in the 1930s to help combat urban sprawl. I believe in them strongly. They make rural experiences so much more accessible to urban dwellers. They help protect countryside that might otherwise go under tarmac, and that in a lot of ways is quintessentially English.
This is the first map I’ve seen that shows how green and belt-like the Greenbelts are.
