The Pitareti monastery consists of the Theotokos church, a belfry, the ruined wall and several smaller accessory buildings. The main church appears to have been built in the reign of George IV early in the 13th century. Its design conforms to the contemporary canon of a Georgian domed church and shares a series of common features – such as a typical cross-in-square plan and a single lateral porch – with the monasteries of Betania, Kvatakhevi, and Timotesubani. The façades are decorated, accentuating the niches and dormers. The entire interior was once frescoed, but only significantly damaged fragments of those murals survive.
The monastery was a property and a burial ground of the noble family of Kachibadze-Baratashvili and, since 1536, of their offshoots – the princes Orbelishvili. A 14th-century inscription mentions a ctitor – the royal chamberlain Kavtar Kachibadze. Another inscription, from a grave stone, records the name of Qaplan Orbelishvili who refurnished the monastery in 1671. The monastery thrived at Pitareti until 1752 when it was forced to close due to a marauding attack from Dagestan.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.
