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:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
