Lezhë Castle dominates the city of Lezhë, northern Albania. The castle originates from Illyrian times. In 1440 it was reconstructed by the Venetians, and in 1522, after the Ottoman conquest, it was also rebuilt by the latter. The castle bears traces of Illyrian, Roman, Byzantine and Ottoman architecture. Interesting places to visit are the ruins of the Ottoman buildings inside the castle, the mosque, the tower of the south-eastern wall with a Roman arch, and the Illyrian tower on the southern wall. The Lezha castle is a cultural monument. The castle offers a beautiful view of the Lezha fields and the Adriatic Sea.
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.
