Lonely fortress

Weoley Castle in Birmingham was revealed to be the least-visited tourist attraction in England, with 5,205 visitors last year. What is there to see?
— It is described as the ruins of a fortified manor house built by the Lords of Dudley as a hunting lodge in the 1270s. Visitors can view the ruins from a platform most days, but can access the stones by special arrangement or for events such as the Easter egg hunt.
