ENGLISH
The Minčeta Tower is the most prominent point in the defense system toward the land. The tower's name derives from the name of the Menčetić family, who owned the ground the tower was built upon. By its height and impressive volume the tower dominates the northwestern high part of the city and the walls. Minčeta Tower was build by a local builder Nicifor Ranjina and Italian engineers sent by Pope Pius II in 1463 at the height of the Turkish treat, originally as a strong four-sided fort. In the middle of the 15th century, around the earlier quadrilateral fort, Michelozzo built a new round tower adapted to the new technique of warfare and joined it to the new system of low scarp walls. The walls of the new tower were full 6 meters (20 feet) thick and had a series of protected gun ports. The architect and sculptor Giorgio da Sebenico of Zadar, continued the work on the Minčeta. He designed and built the high narrow round tower, while the battlements are a later addition. The tower was completed in 1464, and is the symbol of the unconquerable city of Dubrovnik. Since it is the highest point of the wall, it is considered to offer a seemingly "unforgettable" view on the city.
