Grand Hotel in Sopot, Poland was originally built in 1924–1927 at a cost of 20 million Danzig gulden as the most refined hotel in Sopot - the Kasino Hotel. As the Sofitel Grand Hotel, it is located at the seaside of the Gdansk Bay, in the heart of the town and next to the beach. Sofitel Grand Hotel has been totally refurbished during the last years, the classical atmosphere from the earlier period is still present and the hotel is now both classical, and modern. In 2007 it was decided to open Grand Spa by Algotherm, this to maintain the history of Sopot as a Spa resort.
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.
