Otto I, Holy Roman Emperor
The first written mention of Lázně Kynžvart is from 972 as Castelum settlement, when it was donated by Otto I, Holy Roman Emperor to bishop Wolfgang of Regensburg. Building of the castle finished in 1287. The castle soon lost its significance, was occupied by a bunch of thieves and in 1348 was burned to the ground by order of the King Charles IV. In 1398 the castle was built once again.
