The Mariinskyi Palace is the official ceremonial residence of the President of Ukraine. The Elizabethan baroque palace is sited on the right bank of the Dnipro River in Kyiv, Ukraine, adjoining the neo-classical building of the Verkhovna Rada, the parliament of Ukraine.
The palace was constructed by command of the Russian Empress Elizaveta Petrovna in 1744; her architect was Bartolomeo Rastrelli, the most eminent architect working in the Russian Empire at that time. One of the students of Rastrelli, Ivan Michurin, together with a group of other architects, completed the palace in 1752. Empress Elizabeth, however, did not live to see the palace completed; the first senior-ranking member of the Imperial Family to stay in the palace was Empress Elizabeth's niece-in-law, Empress Catherine II, who visited Kyiv in 1787. In the late 18th and early 19th centuries, the palace was the main residence of the Governors-General.
In the early 19th century, the palace burned down in a series of fires, and was in total disrepair and abandoned for almost half a century. In 1870, Emperor Alexander II had the palace reconstructed by the architect Konstantin Mayevsky, using old drawings and watercolours as a guide. It was then renamed after the reigning Empress Maria Alexandrovna. By her wish, a large park was established off the southern side of the palace. The palace was used as a residence for visiting members of the Imperial Family until 1917.
During the years of the Russian Civil War in 1917–20, the palace was used as the Kyiv revkom headquarters, particularly during the Kyiv Bolshevik Uprising. In the 1920s, the building belonged to an agricultural school, soon after which it became a museum. The Mariinskyi was badly damaged during the Second World War, and was restored at the end of the 1940s. Another major restoration was completed in the early 1980s.
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.
