240 horseshoes hang on the walls of the Great Hall. These represent the unique custom that every peer of the realm must give a horseshoe to the lord of the manor on their first visit to Oakham. The custom has been followed for at least 500 years and probably dates back to the 12th century.
The oldest surviving horseshoe is said to have been given by Edward IV in about 1470. The most recent were given by HRH The Princess Royal in 1999, HRH The Prince of Wales in 2003 and HRH Princess Alexandra 2005.
Rutland custom demands that the shoes are hung upside down. Apparently if you hang a shoe the right way up the Devil makes a home in it.
Lord Bonkers adds: And you may have a perfectly good terrier singed getting him out.
