Sapara Monastery has existed from at least the 9th century, and has numbered among its monks many important figures in Georgian ecclesiastical history. At the end of the 13th century Sapara became a possession of the Jakeli family, whose leader, Sargis Jakeli, was adept at staying on good terms with the Mongols, which enabled Samtskhe to enjoy a peace unusual for the time. When he grew old, Sargis took monastic orders and changed his name to Saba. His son Beka built the largest of the 12 churches here, St Saba's Church, named after the saint whose name his father had adopted, one of the most architecturally important churches of its time. The 14th-century frescoes inside are of high quality.
From the end of the 16th century until the beginning of the 17th century the Sapara Monastery became empty due to the expansion of Turkish policy into Samtskhe and during this process the monastery's icons and other treasures were taken to more protected areas of Georgia.References:
The Kalozha church of Saints Boris and Gleb is the oldest extant structure in Hrodna. It is the only surviving monument of ancient Black Ruthenian architecture, distinguished from other Orthodox churches by prolific use of polychrome faceted stones of blue, green or red tint which could be arranged to form crosses or other figures on the wall.
The church is a cross-domed building supported by six circular pillars. The outside is articulated with projecting pilasters, which have rounded corners, as does the building itself. The ante-nave contains the choir loft, accessed by a narrow gradatory in the western wall. Two other stairs were discovered in the walls of the side apses; their purpose is not clear. The floor is lined with ceramic tiles forming decorative patterns. The interior was lined with innumerable built-in pitchers, which usually serve in Eastern Orthodox churches as resonators but in this case were scored to produce decorative effects. For this reason, the central nave has never been painted.
The church was built before 1183 and survived intact, depicted in the 1840s by Michał Kulesza, until 1853, when the south wall collapsed, due to its perilous location on the high bank of the Neman. During restoration works, some fragments of 12th-century frescoes were discovered in the apses. Remains of four other churches in the same style, decorated with pitchers and coloured stones instead of frescoes, were discovered in Hrodna and Vaŭkavysk. They all date back to the turn of the 13th century, as do remains of the first stone palace in the Old Hrodna Castle.
In 2004, the church was included in the Tentative List of UNESCO"s World Heritage Sites.
