The Île Sainte-Marguerite island is most famous for its fortress prison (the Fort Royal), in which the so-called Man in the Iron Mask was held in the 17th century.
The island is first known to have been inhabited during Roman times, when it was known by the name Lero. In 1612, ownership of the island passed from the monks of Saint-Honorat to Claude de Lorraine, Duke of Chevreuse. Shortly after, construction of a fort on the island (to become the Fort Royal) began. In 1635, the island was captured by the Spanish and recaptured by the French two years later.
Towards the end of the 17th century, the Fort Royal became home to a barracks and state prison. During the 18th century, the present-day village of Sainte-Marguerite developed, thriving on the spending power of the soldiers stationed on the island.
The Fort Royal was home to a number of famous prisoners until its closure in the 20th century. As well as the Man in the Iron Mask, a mysterious prisoner whose identity remains unknown, Abd al-Qadir al-Jaza'iri (an Algerian rebel leader), Marquis Jouffroy d’Abbans (inventor of the steamboat) and Marshal Bazaine (the only successful escapee from the island) have all spent time there.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
