Dunyvaig Castle was built on top of an ancient fort or dun in the 12th century. Forfeited in 1493, the castle passed to the MacIans of Ardnamurchan. Afterwards the castle was leased to the MacDonalds, then the Campbells and back to the MacDonalds.
In the 17th century Dunyvaig was conquered several times by the English and Scottish armies. The castle was seized in 1647 by the Covenanters and passed into the hands of the Campbells of Cawdor, who held it until 1677, when Sir Hugh Campbell pulled down the castle and moved to Islay House.
Today all that remains of the castle are mainly the ruins of the sixteenth-century castle, although the site includes a thirteenth-century courtyard, and a fifteenth-century keep.
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.
