Herblingen Castle in Stetten was probably built at the beginning of the 13th century by the Lords of Herblingen. In 1281 Konrad von Herblingen rebuilt the chapel, which may have been existed already in the 11th century. Herblingen family died out in the 15th century and after then castle owners changed many times.
The bank director Johann Wilhelm Gestefeld from Vienna acquired the castle in 1733 and converted it into a residence. By removing the battlements, drawbridge and ring wall he completely changed the appearance of the medieval castle. The trenches were also filled. The oldest existing part of the castle is probably the keep from the 13th century.
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.
