Kildonan Castle stands on the southern coast of the Isle of Arran. The castle's name is derived from the name of a former resident, Saint Donan, who is said to be buried on the island. It was built in the 13th century by the MacDonalds, the Lords of the Isles. The castle stands on the cliffs, overlooking the island of Pladda and the entrance to the Firth of Clyde. It was built to defend against enemies attacking through the Firth. The castle was used as a hunting lodge by the Kings of Scotland, including Robert III, when the island belonged to the crown. The castle became the property of the Earls of Arran in 1544.
Kildonan castle stands out on the old raised beach behind and above the village. It was once, with Lochranza Castle and Brodick Castle, one of three fortresses guarding Arran's strategically important position in the approaches to the Clyde. Today's Kildonan Castle is only a shadow of its former self, but still reflects its origins as a 13th Century keep.
The castle was originally built by the Lords of the Isles, but by 1406 was in the ownership of Robert III, who in that year passed it on to his illegitimate son, John Stewart of Ardgowan. In 1544 it was acquired by the Hamilton family, the Earls of Arran.
Kildonan Castle has long been ivy clad and unstable, making close examination a dangerous proposition. It also stands in the garden of a house, meaning that it can only be seen from a nearby right of way leading to the beach. Not far from the castle is an increasingly ruinous lookout tower, a relic from Kildonan's days as the location of Arran's only Coastguard station, which moved to Lamlash in 1981.
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.
