Oakham Castle is the best preserved 12th-century building in Britain. But there's much more to it than meets the eye. The walled area surrounding the castle is full of mysterious lumps and bumps crying out to be investigated. The castle was once home to the Norman knight Walkelin de Ferrers, who fought alongside Richard the Lionheart in the Crusades. Before that, the same site was home to some of our most legendary Saxon Kings and Queens. Time Team's task is to find out about the many buildings that would once have surrounded the castle, and they're particularly excited about the prospect of finding de Ferrers' long-lost private quarters.
