The Sopot Pier, built as a pleasure pier and as a mooring point for cruise boats, first opened in 1827. The next reconstruction extended the length of 150 metres, then to 315 m. The pier was brought to the contemporary length in 1928, along with the walking passage of the spa. The first non-wooden elements appeared after 1990, when the head was modernised using steel elements.
At 511.5m, the pier is the longest wooden pier in Europe. It stretches into the sea from the middle of Sopot beach which is a popular venue for recreation and health walks (the concentration of iodine at the tip of the pier is twice as high as on land) or public entertainment events, and it also serves as a mooring point for cruise boats and water taxis. It is also an excellent point for observing the World Sailing Championship, the Baltic Windsurfing Cup and the Sopot Triathlon taking place on the bay. Sopot pier consists of 2 parts: the famous wooden walking jetty and the Spa Square on land, where concerts and festivities are organised.
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.
