Hazmburk (14 km southwest of Litoměřice) A Gothic castle built after 1300 originally called Klapý. It was considerably extended after 1335 by the family of Zajíc from Valdek (hence the name Hasenburk) who received the castle from the King Jan Lucemburský. The two high towers (a prism one and a cylindrical one) date from this period; they are standing on the steep hill till these days. Both the castle and the settlement below it were abandoned as early as during the Hussite wars.
