21799 Ciociaria           Discovered 1999 Oct. 1 by F. Mallia and G. Masi at Campo Catino.
La Ciocia, from which the name is derived, is the ancient footwear of the early inhabitants of the Campo Catino area of southern Latium. The area is now nearly coincident with the Province of Frosinone, which permitted the Campo Catino Astronomical Observatory building.
