Leuchtenburg Castle (Castelchiaro) above Lake Caldaro towers into the sky in the surroundings of Castel Varco in the locality of Vadena. The castle was probably constructed in 1250 by the Lords of Rottenburg. The castle complex has been protected by a circular wall which protected the castle complex from assaults. Due to the fact that the position of the castle is not really well-protected it has presumably been constructed in order to impress.
Numerous castles of the Rottenburg leadership have been razed after the conflicts with Frederick IV, Duke of Austria, in 1410, but not Leuchtenburg, which was handed over to the sovereigns and in the following years was lent to officials of Caldaro. After 1610 Leuchtenburg remained uninhabited and started decaying.
Only in the 20th century the walls of the ruins were conserved. Leuchtenburg consists of a circular wall inside which there were several residential buildings. However, today these buildings could only be preserved to some extend. However, there are also well-preserved rests of the great hall with frescos dating back to the 15th century.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.
