Vanis Kvabebi is a cave monastery in Samtskhe-Javakheti region of Georgia near Aspindza town and the more famous cave city of Vardzia. The complex dates from 8th century and consists of a defensive wall built in 1204 and a maze of tunnels running on several levels in the side of the mountain.
There are also two churches in the complex. A newer stone church that is in quite good shape stands near the top of the wall, and a smaller, domed church that clings to the rock on the level of the highest tunnels.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
