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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
