Mon Repos or 'Monrepos' is a manor house and landscaped English park in Vyborg. Between 1788, when Ludwig Heinrich von Nicolai bought it, and 1943, 'Monrepos' was owned by the family of Baron Nicolai (better Nicolay). The historic core of the museum complex is a manor from the early 19th century. This consists of the Main house and the Library house, monuments of wooden classical architecture, and the landscape rock park designed in the romantic style, and which remains a unique monument of gardening art. Among the park designers were such architects as J. Martinelli, Auguste de Montferrand, A. Shtakenshneider, Ch. Tetam, artists Ya. Mattenleiter, and P. Gonzago. The area of the park is marked by special physical and geographical features, like the old Wiborgite granite, which is named after Vyborg, and glacial formations of up to 20 metres high. In this nature reserve, 50 species of different plants can be found, some of them being rare. Its fauna is diverse as well: the park abounds in numerous birds and animals.
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.
