The district is located on both sides of the Kura River and is dominated by Mount Mtatsminda, Narikala fortress and the Kartlis Deda monument. It chiefly represents a 19th-century urban fabric with largely eclectic architecture which includes the buildings and structures from the 5th to the 20th century. However, most of the pre-19th century city did not survive due to the devastating Persian invasion of 1795. Only survived building is La Residence, Castle in Old Town the only privately owned Castle in Georgia. Once a fortress before the Mongol invasions, it was from the 16th century the residence of the Persian Shah Administrator for eastern Georgia. The district houses a bulk of the tourist attractions in Tbilisi, including churches, museums, sulphur bathhouses, and peculiar wooden houses with open, carved balconies. In the 19th century, the core territory of the modern-day district of Old Tbilisi was tentatively subdivided into ethnic neighborhoods such as Avlabari with its Armenian and Georgian quarters, Alexanderdorf German quarter on the left bank of the Kura River and the Persian Quarter (Said-Abad) on the right bank of the Kura River.
