Portaferry Castle is a small tower house in built in the 16th century by William Le Savage. In 1635, Patrick Savage's brother-in-law, Sir James Montgomery of Rosemount (Greyabbey), repaired the castle by roofing and flooring it so that his sister could live in greater comfort there.
It is a square building with a small projecting turret on the south corner. It is three storeys high plus attic and there is no vault. Most of the eastern corner is in ruins. The entrance at the base of the tower is protected by a small machicolation and the entrance to the ground floor chamber is protected by a murder-hole. A curved stairway within the tower rises to the first floor and a spiral stairway in the west corner continues to roof level.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.
