Glenbuchat Castle is a historic Z plan Scottish castle built in 1590 for John Gordon of Cairnbarrow to mark his wedding. It is located above the River Don, near Kildrummy, Aberdeenshire. The building is roofless, but otherwise in fairly good repair.
The family sold the castle in 1738, and it remained in private hands until the 20th century. James William Barclay bought the castle in 1901, and Colonel James Barclay Milne, his grandson, placed it in state care in 1946. A local club purchased the surrounding parkland in 1948 and gave it to the state to ensure that the castle's surroundings would remain intact. Both the castle and the surrounding land are managed by 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.
