Arnot Tower is a ruined 16th-century castle. The current building dates from c. 1507, though fortifications were present c. 1400. The castle has four storeys and a vaulted basement. It was built by the Arnot family who have records dating back to 1105. David Arnot of Fyfe was one of 2000 noble landowners required to swear allegiance to King Edward I of England in 1296. Nicol Arnot Arnot was a loyal supporter of King Robert the Bruce. Robert Arnot was killed in the battle of Flodden in 1514. The Arnots abandoned the old tower around 1700.
In 1760 local poet Michael Bruce wrote a poem about the true story of a love affair between an Arnot daughter and a Balfour of nearby Burleigh Castle. The families were in a feud, and it is believed the daughter of Arnot eloped to Burleigh 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.
