The Bollerup estate was first time mentioned in 1130. The castle was built in the end of 15th century. The present living quarters were built in the 1840s. It lies on an islet and is surrounded by a moat.
Bollerup has been owned by several families like Thott, Gjöe and Rantzau. Today it houses the Bollerup Agricultural Institute. Guided tours of the fort, grounds, stables and church are available during the summer.

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.
