Miholjska prevlaka, also known as 'Island of Flowers', includes a monastery dedicated to Archangel Michael. It was founded by Serbian Archbishop Sava (s. 1219–35). The church base was built earlier, reconstructed in the 9th century and destroyed in the 11th century. The monastery was the seat of the Eparchy of Zeta between the 13th and 15th centuries.
Under planned restoration, the monastery was destroyed by the Republic of Venice in 1441 after it was proclaimed unsafe due to the rumors of a plague breakout. Recent research by the Military Medical Academy in Belgrade, using recovered remains of monks from that time have revealed that the monks died probably due to arsenic poisoning. There are remains of the church base.
Miholjska prevlaka was a tourist resort for Yugoslav military personnel, closed for general public in the Socialist Yugoslavia period.
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.
