11364 Karlštejn           Discovered 1998 Mar. 23 by P. Pravec at Ondřejov.
The Gothic castle at Karlštejn was built in 1348 by Charles IV in the Kingdom of Bohemia, 27 km from the capital, Prague, to guard the crown jewels and state charters. The castle has survived well preserved to the present day, and it symbolizes Czech statehood within Europe. The name was suggested by Z. Ceplecha.
