For the unrelated style that emerged in the English-speaking world during the reigns of successive kings George, see Georgian architecture. The architecture of Georgia refers to the styles of architecture found in Georgia. The country is exceptionally rich in architectural monuments. Characteristic features of the Georgian architecture are monumentality, clear composition, strict proportions, moderate use of decorations, and above all these the harmonic interaction with nature. Georgian architecture is influenced by a number of architectural styles, including several each for castles, towers, fortifications, palaces and churches. The Upper Svaneti fortifications and the castle town of Shatili in Khevsureti are among the finest examples of medieval Georgian castles. Georgian medieval churches have a distinct character, though related to Armenian and Byzantine architecture, typically combining a conical dome raised high on a drum over a rectangular or cross-shaped lower structure. Often known as the "Georgian cross-dome style," this style of architecture developed in Georgia during the 9th century. Before that, most Georgian churches were basilicas. One distinguishing feature of Georgian ecclesiastical architecture, one which can be traced back to a high emphasis on individualism in Georgian culture, is reflected in the allocation of space inside the churches. Other examples of Georgian ecclesiastic architecture can be found overseas, in Bulgaria (Bachkovo Monastery built in 1083 by Georgian military commander Grigorii Bakuriani), in Greece (Iviron monastery built by Georgians in the 10th century) and in Jerusalem (Monastery of the Cross built by Georgians in the 9th century). Other architectural styles in Georgia include the Hausmannized Rustaveli Avenue in Tbilisi and that city's Old Town District. History The history of construction in Georgia can be traced back to the 5th-4th millennia BC, from Paleolithic to the Late Medieval times. The oldest structures were made of stone and wood, and later of bricks. 7th century This was the period of considerable rethinking of church internal space. It was increased by introduction of pillars that held now the tholobate, which gave possibility to experiment with the walls and improved esthetic perception of the interior. Traditional triangular niches by the sides of the apse also appear in this century. First such example, which actually started new traditions, was Tsromi church. 10th century The first hints of the emerging 11-13th century architecture appear in this period in Kumurdo Cathedral. 11th century From the beginning of the century Georgian architecture becomes exceptionally artistic and decorative. Facades acquire rich relief ornamentation
