The Château de Monte-Cristo is a writer's house museum located in the country home of the writer Alexandre Dumas. The château was built in 1846 by the architect Hippolyte Durand. Dumas named it after one of his most successful novels: The Count of Monte Cristo (1845–1846). Durand also built a writing studio on the grounds, which Dumas named the Château d'If after another setting from the same novel. In 1848, short of money, Dumas had to sell the property.
The château fell into disrepair by the 1960s, it was restored with the patronage of King Hassan II of Morocco, who financed the restoration of its Moorish room. Since 1994, the two châteaux and gardens have been restored. The entire property is operated as a public historic museum memorializing Dumas.
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.
