The splendid Great Hall of Oakham Castle is one of the finest examples of late 12th century domestic architecture in England. It was built by Walkelin de Ferrers, a Norman baron, in about 1180-90. The remains of other parts of this fortified manor house lie beneath the grass of the inner bailey. It was surrounded by earthen banks and stone walls which had at least two towers. To the north were gardens and fishponds
The hall posseses a range of 12th century figure sculpture. Above the capitals of its fine columns there are six musicians, each playing a different instrument. Although damaged, they are of superb quality. Almost certainly, the stonework was carved by masons who had worked at Canterbury Cathedral. They used local stone from Clipsham.
