Keila Church is the biggest medieval country church in Harju county, which was obviously established shortly after the North Estonia was occupied by Danes. In 1280 a spacious square chapel was established at "Keila hill", where today there is the chancel of the church. Fragments of the paintings at the chancel walls date possibly from this period already. The main body of the church remained unbuilt at the beginning and was obviously established at the first half of the 14th century. As the influence of the Dominican order, the main body of the church was simple unvaulted box-like building.
The church was expanded in the 15th century. First the massive west-tower was built. Three-sided ending was added to the chancel, it was re-vaulted and altar table of stone was made. In 1480 southern portal was established. In 1489 the church was vaulted and it became two-aisled, which is rather seldom in Estonian churches. The church of Keila was destroyed at the Livonian War in 1558 and the interior was stolen. It was restored in 1596.
There are several chapels in the graveyard, which have been built after 1772 due it was no longer allowed to bury inside churches.
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.
