Duntrune Castle is thought to be the oldest continuously occupied castle on mainland Scotland. It was originally built by the MacDougall clan in the 12th century, along with several other castles in the area, including the MacDougall stronghold of Dunollie Castle near Oban. Duntrune Castle was eventually taken by the Clan Campbell. In 1644, the castle was besieged by the rival MacDonalds, under Alasdair Mac Colla. The Campbells sold Duntrune in 1792, to the Malcolms of Poltalloch. The castle is now owned by Robin Neill Malcolm, current clan chief of the Clan Malcolm.
The curtain wall of the castle dates from the 13th century, although the tower house which forms the main part of the castle is of the 17th century. The castle was renovated in 1954.
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.
