Ardvreck Castle is thought to have been constructed around 1590 by the Clan MacLeod family who owned Assynt and the surrounding area from the 13th century onwards. Clan MacKenzie attacked and captured Ardvreck Castle in 1672, and then took control of the Assynt lands. In 1726 they constructed a more modern manor house nearby, Calda House, which takes its name from the Calda burn beside which it stands. A fire destroyed the house under mysterious circumstances one night in 1737 and both Calda House and Ardvreck Castle stand as ruins today.
Ardvreck Castle was a rectangular-shaped keep comprising three storeys. Under the castle the vaulted basement is pierced by gunloops and the round stair turret is corbelled out to support a square caphouse. Despite the small size of the ruined tower, Ardvreck was originally a large and imposing structure and it is thought that the castle included a walled garden and formal courtyard. The remains of the foundations can still be seen and cover a large area. Unfortunately, all that remains today is a tower and part of a defensive wall. When the waters of the loch rise very high, the peninsula on which the castle stands can be cut off from the mainland.
The castle is said to be haunted by two ghosts, one a tall man dressed in grey who is supposed to be related to the betrayal of Montrose and may even be Montrose himself. The second ghost is that of a young girl. The story tells that the MacLeods procured the help of Clootie (a Scottish name for the Devil, deriving from 'cloot', meaning one division of a cleft hoof) to build the castle and in return the daughter of one of the MacLeod chieftains was betrothed to him as payment. In despair of her situation, the girl threw herself from one of the towers and was killed.
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.
