Ventlinge Church, dedicated to St. Lawrence, was built during the first half of the 1100's. It began as a towerless vestibule church of Romanesque style. Around the year 1200, a defensive tower entirely on its own grounds was added. Above the staircase entrance in the porch is a throw shaft straight up through the wall. Church defenders could also stand on the tower’s second floor and throw stones at unwelcome visitors. In 1812, the church was repaired and rebuilt so its medieval character was lost. The lantern was added to the tower in 1825.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.
