Trimburg is a hilltop castle in Lower Franconia, built by Gozzwin of Trimberg in 1135. Originally the castle was formed by three different sub-structures that came from different periods of time. The ruins preserved today are from the last time period.
The oldest part of the castle was named Leuchtenburg or Alte Burg. During the Peasant's War in 1525 the castle was captured and destroyed. Also during the Thirty Years' War, the castle suffered a new destruction. Afterwards the castle Trimburg was rebuilt from scratch with a new architectonical character of a palace.Through the fact that the surrounding country was in neediness of stones, it was partly deconstructed and the building material was used for building new houses in the towns.
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.
