Simuna church is one of the oldest in Estonia although its exact building time is unknown. It has been destroyed in wars and rebuilt again several times during centuries, at least in 1728-29 and also 1885-86. From the old church has remained part of a tower that was used on protective purposes. The altar was made by C. Ackermann, a famous wood carver and the altarpiece was made by Carl Sigismund Walther. The organ was built by Gustav Normann and so it is one of the oldest organs made by an Estonian. Visitors can visit a platform on the top of the bell-tower and enjoy a marvelous view on surroundings. The tower is 53,5 m high.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.
