The Krujë castle was the center of Skanderbeg's rebellion against the Ottoman Empire. During the Albanian Revolt of 1432-1436 the city was unsuccessfully besieged by Andrea Thopia and Ottoman rule was restored. After Skanderbeg's rebellion in 1443 the castle withstood three massive sieges from the Turks respectively in 1450, 1466 and 1467 with garrisons usually no larger than 2,000-3,000 men under Skanderbeg's command. Mehmed II 'The Conqueror' himself could not break the castle's small defenses until 1478, 10 years after the death of Skanderbeg. Today it is a center of tourism in Albania, and a source of inspiration to Albanians.
Inside the castle is the Teqe of Dollme of the Bektashi (an Islamic Sufi sect), the National Skanderbeg Museum, the remains of the Fatih Sultan Mehmed mosque and its minaret, an ethnographic museum and a Turkish bath.
Another attraction for tourists is the Ethnographic Museum, located in the south side of Kruje Castle. This museum is designed based on a typical house of 19th century. It reveals the sustainable methods of tools, food, drink and furniture production in a typical household. There are also objects and old wood and metal supplies that represent the lifestyle back then in the castle.
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.
