The Christina church (or German Church) was consecrated in 1648 and named after Queen Christina. The octagonal chapel for Rutger von Aschenberg was built in 1681, possibly by Erik Dahlberg. The tower, designed by Carl Fredrik Adelcrantz 1780, rises powerfully over the lower urban buildings around it. It became an important symbol of the great German Assembly which included the Dutch who over a period in the 1600s represented a fifth of the city's population. Although the church was burnt on several occasions it managed to keep the walls of Dutch tiles from the 1630s. In an extensive renovation in 2001 the facades was covered with yellow plaster.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.
