The ship's badge of HMS 'Oakham Castle', 1944. Official design approved in April 1954. It depicts on a red field, four gold interlaced horsehoes. The badge is round, with a gold rope twist border and naval crown representing a corvette. It is made of cast brass, painted excepting the crown and border. There are three bolt holes on the reverse. 'OAKHAM CASTLE' is inscribed on the name tablet and impressed on the reverse, on which, is painted in white: '4160, 10.7.57.' Noblemen on their first visit to Oakham in Rutland had to pay a fee in the form of a horseshoe to the Lord of the Manor. Today, it is the custom to hang a outsize ceremonial horseshoe in the great hall of the castle to celebrate royal visits and other notable occasions. The custom relates to the arms of the De Ferrers family. The castle itself is actually a fortified manor house.
