The Katskhi monastery is an
octagonal building of more complex design than other similar polygonal Georgian monuments such as
Gogiuba, Kiagmis-alty, Oltisi, and
Bochorma. The exterior of the church features three gradually narrowing cylindrical levels formed by the faceted
gallery, the main body of the church, and the
drum of the
dome. The six
apses are inscribed into the outer polyhedron and surrounded by an
ambulatory from all sides. An inscription from the ambulatory mentions the certain "Tskhovreba, daughter of Ioann, Duke of Dukes". A single spacious interior compartment around the subdome bay includes radially oriented semi-circular apses. One of these, the
altar apse, projects outward prominently due to its large
bema. The drum of the dome is also faceted. Each facet of the main body of the church as well as that of the dome and gallery terminate in a
pediment with three lines of polygonal
cornices. The building was richly ornated, but the decoration of two upper tiers was lost in the process of the 1854 restoration. Of note is a large composition in relief at the southern vestibule of the gallery, the Exaltation of the Holy Cross, featuring a cross supported by four angels. The church is surrounded by a pentagonal wall, which contains a free-standing bell tower in its eastern corner. These structures are later additions, probably from the 17th or 18th century. == History ==
