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 Historic Sausage Kitchen of Regensburg (Wurstküche) is notable as perhaps the oldest continuously open public restaurant in the world. In 1135 a building was erected as the construction office for the Regensburg stone bridge. When the bridge was finished in 1146 AD, the building became a restaurant named Garkueche auf dem Kranchen ("cookshop near the crane") as it was situated near the then river port. Dockers, sailors and the staff of the nearby St. Peter cathedral workshop were the regulars for the centuries to come. The present building at this location dates from the 17th century, but archaeological evidence has confirmed the existence of a previous building from the 12th century with about the same dimensions.
Until ca. AD 1800, the specialty was boiled meat, but when the family who currently own the restaurant took over in 1806, charcoal grilled sausages were introduced as the main dish offered. The kitchen still operates today and serves 6,000 sausages to guests daily.
