Murat Castle in Pizzo was built by the Aragonese in the 15th century. The former King of Naples Joachim Murat, who was the brother-in-law of Napoleon, was imprisoned for several days in the castle and then sentenced to death. He was executed by firing squad on October 13, 1815, in the main hall of the castle and was possibly buried in the church of San Giorgio. Paradoxically, the castle is now called Castello Murat. Inside the castle is the Provincial Museum Murat.
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.
