38684 Velehrad           Discovered 2000 Aug. 25 by P. Pravec and P. Kušnirák at Ondřejov.
According to tradition, Velehrad was the seat of the great Moravian princes and of Archbishop Methodius. Nowadays it is a famous church of pilgrimage, connected to the Cyril-Methodius tradition, although its actual connection to the historic locality is questionable.
