Ottokar I of Bohemia
Budyně nad Ohří is known for its water castle. Originally it was a wooden castle, but it was rebuilt to a Gothic stone castle at the beginning of the 13th century by Ottokar I of Bohemia. King John of Bohemia sold the castle to the noble family Zajícové of Hazmburk, who owned it until 1613. During their rule, the castle and the whole manor prospered and developed. Since 1946, it is owned by the town.
