20513 Lazio           Discovered 1999 Sept. 10 by F. Mallia and G. Masi at Campo Catino Astronomical Observatory.
Lazio is the Italian region containing Rome, the everlasting city. The Regione Lazio allowed the creation of Campo Catino Astronomical Observatory, where this minor planet was discovered. It was the first region in Italy that has approved a law against light pollution.
