On the shore of the Tikves lake (very close to Pravednik village) is the Monastery Polog and the church St. George, a significant monument of culture from 14th century richly decorated with frescoes. Built in the first half of 14th century, in the foothills of Mount Visesnica, nowadays it is on the left bank of Tikves Lake. It is assumed that it dates back to 9th century because the architectural style is very similar to the architectural style of the churches of Ohrid.
Church, standing alone in the beautifully arranged rose garden, was built in a shape of naval construction, with a dome on eight-sided tambour and three-apse from outside. The church is made of stone and bricks, with a nave and porch. The interior of the church is entirely picturesque. It is famous for its 14 century frescos, and even more for the church chandeliers carved in wood, dating from 1492, which is the oldest dated woodcut in Macedonia. Very impressive is the large iconostasis cross with crucifixion made of wood carving in 1584. The throne icons of St. Mary (St. Bogorodica) dating from 1649, 'Jesus Christ – the Savoir with the apostles”, from the beginning of 16 century, as well as the royal gates originating from the end of the century, are of great value.
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.
