In the 13th century, the town of Kadaň was promoted to a 'Royal City'. It began to thrive and a new town was built on the heights above the river, with a castle and Franciscan monastery. The castle was mentioned first time in 1289. It was established as a four-wing Premyslid castle with a housing palace over the river. It served as the seat of the royal burgrave – the administrator of the Kadan region.
The castle was rebuilt in the mid-15th century. After it had been damaged during the Thirty Years Wars, Maria Therese allowed it to be rebuilt as military quarters in 1750. The eastern wing is used for the municipal library with an internet cafe and ceremonial hall. The Josef Liesler Gallery has been in operation since September 2000. A nursing home is situated in another part of the castle.
