Ostroh, or Seeberg in German, is originally a Romanesque castle, which was later rebuilt in Gothic and reneissance styles. The premises consist of the castle itself and farm buildings. The castle itself is formed by Romanesque and Gothic palaces linked by a Reneissance wing with an arcade corridor in the court. The first documented owner of the castle was the Town of Cheb, authorised to manage the Seeberg by the Emperor Karel IV. After the Hussite wars, Emperor Zikmund gave the castle to his chancellor Kašpar Šlik, a Cheb native, for his loyal service. He later left the castle to the noble House of Juncker from Cheb, who were the first in the list of its many later owners.
