Kyminlinna fortress was part of the South-Eastern Finland fortification system built by Russia after Russo-Swedish War of 1788-1790. Kyminlinna and Ruotsinsalmi sea fortress formed together a defense line, which was planned to stop enemies attacking from the west. First fortress was a bastion constructed in 1791-1795 by the general Aleksandr Suvorov. The older part was replaced only couple of years later by the much bigger five-corner caponier fortress (built in 1803-1808). When Russia occupied Finland in the Finnish war, Kyminlinna lost its defensive status. Only real battle in Kyminlinna was fought in the Finland civil war (9.4.1918) between German forces and red guards.
Nowadays the fortress area is owned by the Finnish government and it's open for public.
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.
