Neptune's Fountain, in the center of Dlugi Targ has grown to be one of Gdansk's most recognizable symbols. The bronze statue of the Roman god of the sea was first erected in 1549, before being aptly made into a fountain in 1633. Like the city he represents, Neptune has had a storied history, himself - dismantled and hidden during World War II, old Neptune didn't come out of hiding until 1954 when he was restored to his rightful place in the heart of the city, reminding us of Gdansk's relationship to the sea.
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.
