90892 Betlémská kaple           Discovered 1997 Jan. 16 by M. Tichy at Klet.
Betlémská kaple is a medieval religious building in Prague, notable for its connection with the Czech religious reformer Jan Hus. He served there as an influential preacher from 1402 to 1412. The Chapel bearing the name of Bethlehem could contain almost 3000 people. It was restored in the 1950s.
