Reached through a forest, the domed church of Moni Thari was hidden from view in order to escape the attention of marauding pirates. According to legend, it was built in the 9th century by a mortally ill Byzantine princess, who miraculously recovered when it was completed.
The 12th-century north and south walls remain, and there are vestiges of the 9th-century building in the grounds. The nave, apse and dome are covered with frescoes. Some walls have four layers of paintings, the earliest dating as far back as 1100, while there are three layers in the apse dating from the 12th-16th centuries. These are more distinct, and depict a group of prophets and a horse’s head. The monastery has been extended and has basic accommodation for visitors.
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.
