The Church of Saint Paraskevi is a partially preserved medieval Eastern Orthodox church in Nesebar, a town on the Black Sea coast of Burgas Province in eastern Bulgaria. It was most likely built in the 13th or 14th century and forms part of the Ancient Nesebar UNESCO World Heritage Site. The Church of Saint Paraskevi features a single nave and a pentagonal apse as well as rich exterior decoration. Its dome and the belfry surmounting the narthex have not been preserved today, and it is unknown which of the three saints named Paraskevi it was dedicated to.
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.
