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:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
