Knock Castle is a four-storey ruin, dating from approximately 1600. The external walls of the castle survive intact, although the tower is roofless. The inside of the tower is entirely ruined, but the remains of a vaulted basement, used as a kitchen, and a spiral turnpike staircase can still be seen. An unusual feature at Knock are the defensive shot holes for pistols, of which three are located under each of the numerous windows.
A short distance to the west is a motte, or mound, with the possible foundations of a 12th-century timber stronghold, known as the Old Castle Knock. Belonging to the Earls of Mar, this structure was destroyed in 1590 by the Clan Chattan (Macintosh). What little remains of the site appears to have evidence of a corn-drying kiln within.
Knock Castle was granted to the Gordons of Abergeldie by the 4th Earl of Huntly, after the battle of Corrichie. Fought on the 28 October 1562, the Gordons were defeated by the forces of Mary, Queen of Scots, during her suppression of the rebellious Huntly.
A feud between the neighbouring clan, the Forbes, intensified when Henry Gordon, the 2nd Laird of Knock, was murdered during a raid by the Forbes and Clan Chattan men in 1592. His brother Alexander Gordon succeeded Henry, and may have built or remodelled Knock Castle.
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.
