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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
