Reference Postcode "S11 2YE".
A search for this code returns no results but this is, and has been for some time, the correct postcode for the Shepherd Wheel Museum in Sheffield. The museum is clearly marked on OpenStreetMap.
If it's any consolation, Apple Maps, the AA and even the Royal Mail postcode checker also deny its existence so I suspect an error in a database way upstream.

This is no longer a green area, its is a massive housing development and houses are slowing opening 1 by 1
