Kosava castle is a ruined neo-Gothic castle built in 1830 by Graf Wandalin Puslowski. It is near the palace where Andrzej Tadeusz Bonawentura Kościuszko was born. The architect of the castle was Frantisek Yascholda. The ruined castle is similar to a replica of Tadeusz Kościuszko's house in Merechevschina. After the collapse of the January Uprising in 1863, ownership was transferred to the Trubetskoy family and other Russian aristocrats. During World War I and World War II, the place was severely damaged. Currently, the castle is in the process of restoration.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.
