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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
