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.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
