Camberwell is one of the old south London villages that was absorbed by the expanding city in the 19th century and has never been quite fashionable enough to lose its character. Camberwell Green is still roughly where the village green was; the Georgian houses on Grove Lane still exist; the art college has been producing painters, illustrators, and designers for over a century.
The street market on and around the green on Fridays and Saturdays is the least curated in the area: fruit and veg and household goods and nothing aspirational. Myatts Fields at the walk's end has the apple orchard that gets more attention on heritage charity websites than it does in person, which is how it should be.
