Not sure if anyone is still watching this feed. I believe the building was designed by A Edgerton Leeson and the commission was as a result of a competition. Still trying to track down evidence for that and information about the competition.
The original intention was for a museum commemorating the War I think, but the hall of memory was built instead (as it would be more central).
The museum has had several uses over the years, as a museum of Birmingham, natural history and a nature centre type thing.
Trying to track down more information and images but typing cannon hill in limits the results somewhat! If anyone has anything to add, that would be great!
