Systematic archaeological studies (N.Khoshtaria, O.Lortkiphanidze) carried out in the Vani environs since 1947 revealed the remnants of a rich city of the ancient power of Colchis.

The second phase - end of the 7th and beginning of the 6th to the first half of the 4th century BC - is represented by cultural layers, remains of wooden structures, sacrificial altars cut in the rocky ground, and rich burials.

It is assumed that on this stage Vani was the centre of a political-administrative unit of the kingdom of Colchis.

To the fourth phase (3rd to mid-1st centuries BC) belong defensive walls, the so-called small gate, sanctuaries and cultic buildings (temples, altars sacrificial platforms), and the remains of a foundry for casting bronze statues.

In a town Vani there is a museum (founded in 1985), where some unique pieces of the ancient Colchis are exhibited.
