Château de Gramont was first mentioned in 1329, belonging to the lords of Gramont. The medieval castle was destroyed in 1523 by the troops of Charles V of Spain and reuilt later with Renaissance additions. The gardens and terraces date from the 17th century.
In 1793 , the castle and its outbuildings were confiscated to the Nation and a military hospital was installed there for a few months. The building was empty when it was ravaged by fire in 1796.
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.
