Edin's Hall Broch is a 2nd-century broch near Duns in the Borders of Scotland. It is one of the most southerly broch survivals, which are more typically associated with Northern Scotland.
The broch stands in the northwest corner an Iron Age hillfort which presumably pre-dates the broch. The hillfort consists of a double rampart and ditches, enclosing an oval area some 135 metres by 75 metres. A large circular structure (roundhouse) in the centre of the fort, close to the broch, may have been the most important building before the broch's construction.
It is assumed that the hillfort dates to the pre-Roman Iron Age. The date of the broch is uncertain but it has been speculated that it was built between the two main periods of Roman occupation in Scotland: some time in the 2nd century AD. Excavations at Torwoodlee Broch, also in the Scottish Borders, has shown that it was built and demolished during this period.
Within the hillfort is an array of stone footings marking the positions of houses and other structures. Some of the houses overlie the defences – indicating that they are later than hillfort and may be later than the broch as well.
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.
