Zubi Fortress is located in the village that shares its name (Zubi Village) and stands atop a rocky crag. The main road between Imereti and Lower Svaneti once passed through this region, allowing the holder of the fortress to control the flow of traffic.
One side of the tower adjoins the cliffs, while the other is protected by a river, making it almost impregnable.
Zubi Fortress is mentioned in Vakhushti Batonishvili’s book Kartlis Tskhovreba as Takveri Fortress because the fortress was the residence of Lord Takveri at the time.
The brickwork of the tower walls, made from the reddish rocks of the cliff, is quite varied. To the north of the fortress is a semi-circular military bulwark, while to the east are the remains of a round tower, under which there was once a water reservoir.
The fortress consists of three layers in all. The first was surrounded by a square wall fortified with ditches, the second had a support wall made of stone, and the third must have been on an elevated location, made of crushed stone.
Zubi Fortress retains traces from many different periods and appears to have been renovated in later centuries.
