Because of its central location, the island has been important to the communications and commerce in the region. The settlement of Nötö has been dated to the early 11th century, and the assumption is that vikings stopped by during their travels and possibly even settled on the island.
A culturally and historically valuable village consisting of old farms ('hemman') still exists on the island. In the centre of the village there is a windmill, and a few minutes away from the village harbour there is a chapel, inaugurated in 1757. During the summer season, there is a cafeteria in the old primary school building, where e.g. various art exhibitions are held.

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.
