The Minčeta Tower was built by a local builder named Nicifor Ranjina and Italian engineers sent by Pope Pius II in 1463, at the height of the Turkish threat. Originally as a strong four-sided fort, it is the most prominent point in the defensive system towards the land. The tower's name derives from the name of the Menčetić family, who owned the ground upon which the tower was built. By its height and impressive volume, the tower dominates the northwestern high part of the city and its walls.
In the middle of the 15th century, around the earlier quadrilateral fort, Michelozzo built a new round tower using new warfare technique and joined it to the new system of low scarp walls. The full six-meter thick walls of the new tower had a series of protected gun ports. The architect and sculptor Giorgio da Sebenico of Zadar continued the work on the Minčeta tower. He designed and built the high narrow round tower while the battlements are a later addition. The tower was completed in 1464 and became the symbol of the unconquerable city of Dubrovnik.
After a long excavation, a 16th-century cannon foundry was discovered under Minčeta Tower. It is now a museum. Since Minčeta Tower is the highest point of the wall, it is considered to offer a seemingly 'unforgettable' view on the city.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
