It seems that the house was built at the end of the 2nd century AD. and was destroyed and abandoned after the earthquakes of the 4th century AD. The House of Dionysus occupies 2000 square metres of which 556 are covered with mosaic floors decorated with mythological, vintage and hunting scenes. The magnificent mosaic decorations and the mythological compositions are the main characteristics of this restored Roman villa and it is part of the UNESCO World Heritage Site of Paphos.
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.
