The church of Sastamala in Karkku (dedicated to St. Mary) was built in the end of 15th century. In the Middle Ages Karkku was the spiritual and administrative center for the northern Satakunta area. Unfortunately church was nearly abandoned for decades in the 19th and 20th centuries. During this time for example the floor was destroyed. The church was renovated in 1960-1977 and today it's used mainly for summer ceremonies.
There is a fine collection of historical artefacts in Sastamala church. Oldest items are probably a stone font from the 13th century and the part of gravestone with engraving "1304".
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.
