The Herrenhausen Gardens are a heritage of the Kings of Hanover. The Great Garden has always been one of the most distinguished baroque formal gardens of Europe while the Berggarten has been transformed over the years from a simple vegetable garden into a large botanical garden with its own attractions. Both the Georgengarten and the Welfengarten have been made in the style of English gardens, and both are considered popular recreation areas for the residents of Hanover. The history of the gardens spans several centuries, and they remain a popular attraction to this day.
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.
