Lochranza Castle dates from the 13th century when it was owned by the MacSweens. In 1262, King Alexander III granted the castle and its lands to Walter Stewart, the Earl of Menteith. It is believed that Robert the Bruce landed at Lochranza in 1306 on his return from Ireland to claim the Scottish throne. By 1371, the castle was the property of Robert II. It is thought that at this time it was used as a royal hunting lodge.
During the 1490s, James IV used the castle in his campaign against the Lord of the Isles and the Clan MacDonald. In 1614 it was occupied by James VI and in the 1650s it was used by Cromwell. By 1705, Lochranza Castle was the property of the Hamilton family, after it was purchased by the Duchess of Hamilton. The Hamiltons had owned other estates on the Isle of Arran so eventually sold it to the Blackwood-Davidson family who used it as their principal seat. During the 18th century, the castle fell into disuse and was abandoned. The castle is now in the care of Historic Scotland.
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.
