The Castle of Muro Lucano was originally built by Lombards in the 9th century and later expanded. In 1382 Queen of Naples, Joanna I, died at the castle allegedly assassinated by order of the King of Naples, Charles III.
The castle was damaged by an earthquake in 1694 after which new parts we added and the drawbridge removed. Today parts of it are still inhabited by the Martuscelli family, relatives of Francesco Domenico Lordi who bought the castle in 1830.
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.
