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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
