The castle of Petrelë has a rich history, containing a tower which was built in the 6th century AD.
It is one of the tourist locations close to Tirana that attracts a great number of visitors. The Castle, the prominent wooden structure is a restaurant, is perched on a rocky hill, above the village with the same name. It has a triangular shape with two observation towers. Although it was first built in ancient times, the present building dates from the 15th century.
The Petrela Castle was part of the signaling and defense system of Krujë Castle. The castles signaled to each other by means of fires. During Skanderbeg’s fight against the Ottomans, the Petrela Castle used to be under the command of Mamica Kastrioti, Skanderbeg's sister. Today there is a restaurant inside the castle. The castle site has views of the Erzen valley, the hills, olive groves, and surrounding mountains.
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.
