Bítov Castle is a castle on a steep promotory towering above the meandering River Želetavka, near the Vranov reservoir, in the village of Bítov, some 25 kilometres northwest of Znojmo, Czech Republic. Built in the 11th century, Bítov is one of the oldest and largest Moravian castles.
A Přemyslid fortified settlement originally stood on the site and included the Chapel of Our Lady. The fort was rebuilt in the first half of the 13th century as an impregnable Gothic castle guarding the southern boundaries of the Přemyslid lands. In the 14th century a new inner ward was built along with Late Gothic fortifications. The Lords of Bítov became the new owners of the castle and based themselves here for four centuries. They carried out further improvements to the defensive capabilities of the castle.
