Oru Palace was a palace or castle in the northeastern part of Toila. The castle was originally the holiday home of a Russian merchant, Grigory Jelisejev, and later the summer residence of the Estonian head of state. It was built in the Italian renaissance style by Gavril Baranovski, with park designer Georg Kuphaldt. The 57-room three-story building was completed in 1899. The castle descends towards the river terraces, and also contains riding stables and manege. Alleged construction of the palace and the park was the total cost of 5 billion gold rubles.
After the Bolshevik revolution of October, Jelissejev went to Paris. The land belonging to the castle was not sold as it was farmland. In 1934, Jelissejev was not willing to sell land to private persons, but only in the state. The agreement was finalized on 22 February 1935. Until 1940 it served as the summer residence of the Estonian president Konstantin Päts. On 13th August 1941, a fire caused by the retreating Soviets largely destroyed the palace. Today notable gardens are located here.
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.
