Batres Castle is the main attraction of town. It has a square floor plan and was built in the 15th century, with fired clay on flint foundations. It is peculiar because of the diamond shapes on the corners of the towers, which end in circular terraces at the top. The highest one, the keep, is 25 metres high. In the fortress there is a beautiful iron balcony, as well as an interior Renaissance courtyard with Plateresque galleries. In the castle there is also the so-called Garcilaso fountain, situated under a brick arch, framed by marble plaques with engraved verses.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.
