The village of Chazhashi in Ushguli community, situated at the confluence of the lnguri and Black Rivers, has preserved more than 200 medieval tower houses, churches and castles. The land use and settlement structure reveal the continued dwelling and building traditions of local Svan people living in harmony with the surrounding natural environment.
The origins of Svaneti tower houses go back to prehistory. Its features reflect the traditional economic mode and social organization of Svan communities. These towers usually have three to five floors, and the thickness of the walls decreases, giving the towers a slender, tapering profile. The houses themselves are usually two-storeyed; the ground floor is a single hall with an open hearth and accommodation for both people and domestic animals, the latter being separated by a wooden partition, which is often lavishly decorated. A corridor annex helped the thermal insulation of the building. The upper floor was used by the human occupants during summer, and also served as a store for fodder and tools. A door at this level provided access to the tower, which was also connected with the corridor that protected the entrance. The houses were used both as dwellings and as defence posts against the invaders who plagued the region.
Tamar's Castle in village is believed by local folk tradition to have used it as summertime residence by queen-regnant Tamar of Georgia, r. 1184–1213. There are also two stone churches and several accessory buildings. The churches, one named St. George and the other named the Savior, date from the 10th and 11th–12th centuries, respectively.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
