Tbilisi settled in the fourth millennium BC to the third millennium BC. For the first time in the 4th century AD, Tbilisi has been named as the castle of the city. Tbilisis has always been of regional importance due to its location at the intersection of important roads and the same features have contributed to the expansion of this city from the past.
The city is 120 kilometers from the Great Caucasus Mountains and 250 kilometers from the Black Sea , and is located in the cities of Tashkent , Istanbul , Rome , Barcelona , Boston , and Chicago .
The city is located on the sides of the Meccan River, within wide gates. This river, which originates from the Turkish mountains, is 36 kilometers long in the city. Ortachala dam reduces the flow of water in the city and adjusts its water regime.
The five mountain ranges that flow through the underground waterways sink from the slopes around Tbilisi to the Kura River: the Dagmys Tuskali and the Tsukysis Tchagaly from the Magnificent Golnassi Tsalqy and Lochinits Tsagaly from the east. Two small lakes, Lysi and Ko, are located on the northern slopes of Tbilisi. The “Tbilisi Lake” is located behind the Machat mountain range and is surrounded by the Samghuri Plain. The Minda Mountains of Minda are located in the western Maghreb, and the Sulukai Bluffs in the south and the Makhat Mountain Range in the east of the city. In the northeastern slopes of the Tabor Mountain, there are hot springs of water containing alkali and sulfate compounds.
Tbilisi in the distant past grew first along the banks of the river. Later, with the increase in the construction population, slopes and hills and plains around the river were pulled down, which are located in the north and northeast of the city. The southeastern parts of the city consist of tight streets and old two or three-story houses that form the old town of Tbilisi.
