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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
