13804 Hrazany           Discovered 1998 Dec. 9 by M. Tichy and Z. Moravec at Klet.
Hrazany is the site of an ancient Celtic town in central Bohemia above the Vltava river in a gold-mining region. With an area of about 75 acres, it was settled in the second century B.C. and was destroyed in the first century A.D..
