Motto: 'MULTUM IN PARVO'-Much in little
The arms were officially granted on May 1st, 1950.
The green shield represents the County's agriculture, especially its rich pasture land and the acorn exemplifies the former forest land which at one time covered much of the County, especially on the south side. The horseshoe represents the County's history and hunting association, and recalls the unique collection of horseshoes presented by royalty, peers of the realm, and noblemen passing through the County, which hang on the walls of the famous Castle Hall at Oakham.
The motto ("Much in little") refers to Rutland being by some distance the smallest county in England.
