The Santa Margherita Ligure fortress is located at the foot of a hill on which the Villa Durazzo-Centurione now stands. It was built following a resolution by the Senate of the Republic of Genoa in 1550, and it was meant to defend against raids from the Barbary pirates. It was designed by Antonio de Càrabo, who was also responsible for the construction of the Castello di Rapallo.
Construction began in 1550 and it was completed by September of the same year. Various structural interventions and armament upgrades took place until the early 17th century. After pirate attacks ceased in the 18th century, the fort lost its military importance and only some repair and maintenance works were undertaken.
In the 19th century, there were plans to demolish the building twice: first to build a new municipal building after Rapallo was established as an independent municipality, and then to enlarge the adjacent Calata Vittorio Emanuele. It was restored after World War I and it was dedicated in the memory of the fallen in that war.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.
