The dolmens in Abkhazia seem to have been family burials, earliest of which were constructed in the 3rd millennium BC and the largest of which date to the Middle Bronze Age, probably the first half of the 1st millennium BC.
An oval aperture of around 0.4 m diameter is often found on the lateral walls and floor slabs.
Archaeological artifacts found in the dolmens include axes, spear tips, various headpieces, and pottery.
[1] Georgia has inscribed the dolmens of Abkhazia on its list of cultural heritage and reported a threat of destruction due to the lack of adequate conservation.
