Löwenburg castle was built around 1200 by the Counts of Sayn. Together with the Castle of Blankenberg high above the valley of river Sieg it secured their territory. In the second half of the 13th century the old keep was torn down. Only then the castle whose ruins we see today was built. In the late Middle Ages the Löwenburg went through an eventful history until it fell to the Counts of Berg in 1484. It was destroyed in the Thirty Years 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.
