Nikortsminda Cathedral was built in 1010-1014 during the reign of Bagrat III of Georgia and was repaired in 1634 by the King Bagrat III of Imereti. Three-storied bell-tower next to the Cathedral was built in the second half of the 19th century. Frescoes inside the Cathedral date from the 17th century.
Nikortsminda has a massive dome and has unbroken arcatures as its twelve windows, which are decorated with ornamented architraves. The Cathedral has a form of five apses from inside and the massive dome rest of the on the half-pillar shaped apse projections. The transition to the dome circle is affected by means of pendentives. Altar apse bema and the western passage make the space greater inside. Interior is decorated with frescoes from the 17th century and the rich ornaments, reflecting the mastery of the late-Medieval Georgian ecclesiastic art.
From the outside the Cathedral shapes like a short-armed rectangular cross and has a short segment to the west. The facades of the Cathedral are covered with smoothly hewn stone. Decorations include unbroken arcatures and various rich ornaments including multiple-figured story-telling reliefs and episodes (The Transfiguration, The Judgment Day, The Ascension of the Cross, figures of saint, real or imaginary animals, forming one premeditated program). Nikortsminda has one of the most beautiful decorations from all Georgian churches and cathedrals because several different styles can be seen among them, telling the richness of the selection of motifs and the manner of execution.
The Cathedral is on the Tentative List for status as a UNESCO World Heritage Site.
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.
