Kronburg Castle was first time mentioned in 1227. In the 13th and 14th centuries it changed hands several times between Hohenstaufen and Habsburg vassals. The castle was restored in 1490-1536 by Rechberg family. In 1524 it was occupied by revolting peasants and in 1625-1627 it was passed to Johann Eustach von Westernach.
Kronburg was conquered and partially demolished by French army during the War of the Spanish Succession (1703) and rebuilt in residential style in 1707. Today the castle is owned by the von Vequel-Westernach family and hosts weddings and other events.
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.
