Church of Boris and Gleb was built in 1152, on the orders of Prince Yuri Dolgoruky. It was probably part of the princely (wooden) palace complex, but was only used by Dolgorukii for a few years before he left to become Grand Prince of Kiev in 1155. The village, four kilometers east of Suzdal, was an important town before it was destroyed by the Mongols and declined in stature.
The church, built in limestone probably by architects from Galicia, is a four-piered, three-apse church. It is one of the oldest in the district and one of the few churches built by Dolgorukii that is still extant. It retains fragments of frescoes dating back to the twelfth century. In the medieval period it was the site of a monastery and was then a parish church. The building has been significantly altered over the centuries. It lost its original vaulting and dome (the current roof and small dome date to the 17th century) and the apses are thought to be half their original height (their tops too were lost with the roof); a porch was added in the 19th century.
The church is a part of a UNESCO World Heritage Site 'White Monuments of Vladimir and Suzdal' along with the seven other medieval monuments located in Vladimir and its surroundings, and belongs to the monuments of the Golden Ring of Russia.
The church, along with other structures built around it in later centuries - namely the St. Stephen's Church and bell-tower) appears on a three-ruble silver commemorative coin struck by the St. Petersburg Mint in 2002.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
