The Princely Castle at Bogolyubovo (1158-1165) contains the remains of the 12th century Royal Palace, in the form of the Cathedral of the Nativity of the Virgin and the Staircase Tower of Andrei Bogolyubskii. Bogolyubovo was once the residence of the Prince Andrei Bogolyubsky. Great Prince Andrei spent 17 years of his reign in Bogolyubovo before he was murdered there in 1174. After Prince Andrei's death, Bogolyubovo was ravaged and ransacked by Prince Gleb of Ryazan in 1177. In 1230s, the Mongols destroyed its fortifications.
The cathedral is a 17th century building on the site of the original structure. There is a tent-roofed bell-tower of the 17th century. The Church of the Intercession (1165) on the Nerl River is located at the point of the original river gate of Vladimir. It has a single dome supported on four piers with a helmet dome at the crossing and reliefs on the upper part of the exterior walls.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
