9385 Avignon           Discovered 1993 Oct. 9 by E. W. Elst at the European Southern Observatory.
Named for the city in southeastern France, at the east bank of the Rhône river. In 1309 it became the capital of the Roman Catholic papacy and harbored heretics and criminals. The city is well-known for its Saint-Bénézet bridge, which everyone knows from the song "Sur le pont d´Avignon".
