The Ateni Sioni Church is an early 7th-century Georgian Orthodox church in the village of Ateni, some 10 km south of the city of Gori, Georgia. It stands in a setting of the Tana River valley known not only for its historical monuments but also for its picturesque landscapes and wine. The name 'Sioni' derives from Mount Zion at Jerusalem.
Sioni is an early example of a 'four-apse church with four niches' domed tetraconch (between the four apses are three-quarter cylindrical niches which are open to the central space). The church's cruciform interior measures 24m x 19.22m, and its façades are faced with carved rectangular greenish-gray stones, richly decorated with ornaments and figurative reliefs. The church is not dated but is very similar in design to the Jvari Monastery at Mtskheta, which is generally held to have preceded it, and, hence, has been described by some art historians as belonging to the 'Jvari-type' group of churches. Todosak, mentioned in an undated Armenian inscription on the southern facade as 'I, Todosak, the builder of this holy church' is considered to have been an Armenian architect of the original church or its late 10th-century renovator.
The walls of the church contain the earliest known inscriptions in Nuskhuri or Nuskha-Khutsuri, one of the versions of the early Georgian alphabet, dating from 835. The earliest known examples of Mkhedruli, a currently used Georgian script, are also found in the Ateni Sioni church and date to the 980s. One of the inscriptions on the church commemorates Adarnase I of Tao-Klarjeti, the first documented Georgian Bagratid nobleman who was the father of Ashot I, the founder of the new royal line of Georgia.
Near the church there are the ruins of the medieval fortified town of Ateni (modern-day villages of Didi Ateni and Patara Ateni).
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
