The Orthodox church of St George in Paldiski is a typical example of sacral structures of its era - a stone church with classicist baroque roots, it was built between 1784 and 1787 and was consecrated at the end of that year. However, its history dates back even further: the Paldiski Apostolic Orthodox congregation is considered to have been founded in 1721, when a simple church was constructed here for the soldiers and workmen who had been sent to Paldiski to carry out fortifying work commissioned by Russian tsar Peter the Great. A wooden church replaced the original church (constructed from 1724-1728 to the designs of an architect named Moor) and was consecrated in late 1728 in honor of St George the Martyr.
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.
