Yaroslav's Court (Yaroslavovo Dvorishche) was the princely compound in the city of Novgorod the Great. Today it is roughly the area around the Trade Mart, the St. Nicholas Cathedral, the Church of St. Procopius, and the Church of the Myrrh-bearing Women. The Trade Mart renovated and heavily modified in the 16th and 17th centuries, is all that is left of the princely palace itself. The prince also had a compound called the Riurik's Court (Riurikovo Gorodishche) south of the marketside of the city.
Yaroslav's Court is named after Yaroslav the Wise who, while prince of Novgorod in 988–1015, built a palace there. The Novgorodian veche often met in front of Yaroslav's Court and in 1224 several pagan sorcerers were burned at the stake there.
According to the traditional scholarship, after the Novgorodians evicted Prince Vsevolod Mstislavich in 1136, Novgorod began electing their princes and forbade them from holding land in Novgorod. Yaroslav's Court then ceased to be a princely compound and the prince resided at Riurik's Court. Between 1113 and 1136, the Saint Nicholas Cathedral was built at the court. The cathedral is intact and is the second oldest building in Novgorod after the Saint Sophia Cathedral.
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.
