Krupka castle was probably founded by John of Bohemia sometime around the year 1320 when the king wanted to boost fortifications in the border region with Saxony. King John donated the castle, together with the town of Krupka, the tin mines and Trmice in 1330 to the Meissen noble Thimoteus (Těma) of Kolditz. Thimoteus subsequently purchased the Kirchlice fort and in 1335 made a contract with the Lords of Bergau to adjust the border between the Krupka and Geisberg (Supí hora) estates. Thimoteus was an important figure in King John’s court, accompanying him with other noblemen in his tours of Europe. The Kolditz family held Krupka, with an eight-year pause, until 1504, a total of 166 years.
The castle was founded on a high rocky promontory accessed from the north. A channel was cut at the section where the promontory was lowest to reduce the level further. Above this, the original castle was built with a roughly rectangular north-south facing layout, approximately 20 x 55 m in size. Its dominating square tower (palace) was both residential and defensive in nature, stood in the north-western corner of the castle walls and likely comprised three storeys (its form has not been preserved). Of the rectangular tower in the eastern castle walls, which guarded the path through the town below, only the ground floor with its Gothic pointed entrance remains.
At the end of the 15th century, grand fortifications were built which significantly extended the construction. An entrance alley from the western wall and along the building was probably constructed for castle workers, and two semicircle bastions were also built. In 1695, a house was built onto the first of these in 1695 for the noble upper authority. Although in the 17th century the castle itself no longer fulfilled its defensive and residential roles and its remains fell into disrepair, life on the promontory continued. The Krupka estate’s authorities and upper administration were based in the official house.
The Romantic era of the 19th century rediscovered the derelict castle, with the whole area and surroundings being repaired and opened to the public, and the official house turned into a restaurant. It was visitors to the Teplice spas in particular who used the site for trips and relaxation, and they admired the roses in the manor gardens. More than 100 varieties grew there, and this is why the castle began to be known as the Rose Castle (Růžový hrad – Rosenburg). A constant problem, however, was the crumbling castle walls and how to secure them.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.
