Samtavro Transfiguration Orthodox Church and Nunnery of St. Nino in Mtskheta, Georgia, were built in the 4th century by King Mirian III of Iberia. The church was reconstructed in the 11th century by King George I and Catholicos-Patriarch Melkisedek. The famous Georgian Saint monk Gabriel is buried in the yard of Samtavro Church.
Samtavro is part of the UNESCO World Heritage Site of Historical Monuments of Mtskheta.
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.
