The Espoo Cathedral is a medieval stone church built in the last half of 15th century. The church is thus the oldest preserved building in the city. The church was originally designed in by an unknown "Espoo master" and built between 1485 and 1490 under his supervision.
The only remaining parts of the medieval church are the eastern and western parts of the nave. The weapons room was removed between 1804 and 1806 and certain other parts of the church, including the original sacristy, were taken apart between 1821 and 1823 when the building was converted into a more spacious cruciform church.
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.
