One of the most significant monuments of the island of Hvar is definitely the fortified church in Vrboska, erected in 1571, after the Turkish attack on the location of an older church that originated in 1465.
The church has the shape of a fort with an observation post and a loop-hole and from its top there is a beautiful panoramic view of the surrounding places and fields. The church preserves valuable works of Stefan Celesti, Antonio Sciuri, Giuseppe Alabardi, Marko Rašica and Celestin Medović.
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.
