Archangel Michael's Church was built in the 12th century for the newcomers who were settling down in the neighbourhood of Znojmo Castle. The consecration to Archangel Michael and the location on the highest point of Znojmo seem to imply that this church might have replaced an ancient pagan occult place. However, the medieval history of the church does not seem to be free from dramatic events: in the early-15th century the Hussites bombed the church so it had to be built anew. In the 16th century Lutheran preachers got hold of it, when the church tower collapsed for the first time (1581). In 1624 the Jesuits took over the ravaged place and rebuilt it. In 1642 the church tower collapsed for the second time, not to be built again as part of the church structure. In 1852 they built a new tower separately from the church.
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.
