The Tihany Abbey is a Benedictine monastery established at Tihany in the Kingdom of Hungary in 1055 by King Andrew I of Hungary. Its patrons are the Virgin Mary and Saint Aignan of Orleans. King Andrew was buried in the church of the monastery in 1060. His tomb in the crypt of the church is only grave of a medieval King of Hungary which has been preserved until now. The church's ceiling is decorated with frescoes by Károly Lotz, depicting Faith, Hope and Love.
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.
