Since my post the other day Sheffield Castle
about archaeological work on the site of the medieval stronghold I have come across a more detailed account of the various excavations of the site, proposals to perhaps make the site accessible and a CGI reconstruction of the gatehouse. It is from the local newspaper - hence no doubt the ‘local pride’ about its importance - and can be seen at Sheffield's lost castle was 'medieval stronghold' and 'deserves place in history alongside Tower of London'
I have also come across a post from Wessex Archaeology who have been involved in the work on the castle. This is a very good synthesis of the reports since the 1920s on the site and presented in a striking way, with plans and photographs. It can be viewed at Sheffield Castle
