12406 Zvíkov           Discovered 1995 Sept. 25 by M. Tichy and Z. Moravec at Klet.
The Zvíkov castle was built by the Přemyslids dynasty above the confluence of the Vltava and Otava rivers in the thirteenth century. The castle was partly rebuilt in the Renaissance style in the sixteenth century by the Švamberk family. In the nineteenth century the castle was repaired by the Schwarzenbergs.
