English: Great Hall, Oakham Castle, Oakham. 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 possesses 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. The castle was the residence of the lord of the manor of Oakham. Sometimes the king held the manor himself and visited the castle. By the early 16th century many of the buildings were ruinous. However the Great Hall continued in use as a courtroom, the hub of both the manor of Oakham and County of Rutland. Assize courts were held here until 1970. Today, occasional Crown Courts and Coroner's Inquests still take place. Over 200 horseshoes hang on the walls of the castle. These represent the unique custom that every peer of the realm, on their first visit to Oakham, must forfeit a horseshoe to the lord of the manor. The custom has been followed for at least 500 years, and it probably originated soon after the Norman Conquest in 1066. The oldest surviving horseshoe is probably the large elaborately wrought horseshoe headed by a plain shield put up by Edward IV in about 1470. The most recent were given by Lord Lane, then Lord Chief Justice, in 1981, by the Earl Ferrers in 1997, by HRH The Princess Royal in 1999, by HRH The Prince of Wales in 2003 and by HRH Princess Alexandra 2005.
