Junkarsborg was a medieval castle in Raasepori. There are no documents left of castle, but archaeologists suppose that the castle was built in the early 14th century and was used until the beginning of the 15th century. Iron and bronze items, ceramics and silver coins have been found from the castle site. Remains refers to Rheinland in Germany and one theory believes that the castle was originally built by the Danish soldiers.
Nowadays there are only rectangular earth walls left. The ruins are on a forested island in the middle of the Svartå river and can only be reached on foot. Some reconstruction work has been done during 2005-2006 to improve the access to the island and its visual appearance.
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.
