The Church of Christ Pantocrator is a medieval Eastern Orthodox church in Nesebar, on the Black Sea coast. It is usually dated to the late 13th or early 14th century. The church, today an art gallery, survives largely intact and is among Bulgaria's best preserved churches of the Middle Ages.
The best-known feature of the Church of Christ Pantocrator is the rich and colourful decoration of its exterior walls. The most lavishly decorated part of the church is the east side with the apse, and as a whole all sides of the church exhibit different ornamentation. Interchanging strips of three or four rows of bricks and carved stones, which create an optical pattern, are the most basic type of decoration used.
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.
