During the rule of the Venetians the Church of St. Maria was built in the Old Town in 1510. It was turned into a Mosque of the Sultan Selim II as soon as the Turks conquered Ulcinj in 1571. It used to be the so-called Xhamia Mbretrore – Imperial Mosque, as it did not have any Wakf from which it could have been financed at the beginning, so that its employees were paid from the state budget.
Hajji Halil Skura added a minaret in 1693 made of nicely cut stone, in the lower part, on a rectangular base, which was made narrower on top. The religious purpose of this mosque ended in 1880, when the Montenegrins liberated Ulcinj. This religious building also had a maktab. All the Ulcinj reises (captains) would gather there when an important decision had to be made.
This building is the most beautiful monument incorporating a combination of the West and the East in the architecture of Ulcinj. It hosts the town museum.
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.
