A recognisable symbol of Nin is the Church of St Nicholas, located in the field of Prahulje, it is very important for the rulers of the Croatian dynasty and for the history of Croatia and Nin. According to tradition, seven Kings were crowned in Nin, and every crowned ruler rode on horseback to the Chruch of Saint Nicholas, and it was in fact here that he would be presented to the people by the same symbolic ritual-on that mound he would cut with a sword the four corners of the world.
The small church is built on an earthen mound which rises above the wide field, and it is just here on this place that the visitor can experience an unforgettable sunset. In the mound can be found, as yet, unexcavated prehistoric graves. Due to the danger from the Turks as an addition to the church, a defence crown with 8 battlements was built in the 16-17th century, which served as a watch tower. The Church of Saint Nicholas is the only preserved example of the early-Romanesque architecture of such form in Dalmatia, which dates from the end of the 11th and the beginning of the 12th century.
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.
