Beška is a Serbian Orthodox monastery on Beška island on Skadar Lake. It has two churches within its complex, the Church of St. George and the St Mary's Church.
The Church of St. George was built at the end of the 14th century by Đurađ II Balšić the Lord of Zeta from 1385 to 1403. His widow Jelena Balšić reconstructed it before she built St Mary's Church.
The St Mary's Church was built in 1439/1440 as the legacy of Jelena Balšić which is also confirmed by the inscription on the monastery. Jelena died in Beška monastery and was buried in the St Mary's Church.
The sacred bones of Jelena Balšić were placed in new relic case made of stone after the Church of Holy Mother she built on Beška island was reconstructed in 2002.
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.
