The history of Kyminkartano estate starts around 1350, when Earl Erengisle Suneson acquired some farms around the branches of Kymijoki river. He donated the estate in 1370 to Seneschal Bo Jonsson Grip, who was one of the most powerful noblemen of the kingdom. Late Grip donated Kyminkartano to Vadstena Abbey.
King Gustav Vasa visited in Kyminkartano in 1555 and acquired it to the Crown. After Russia had conquered the area in the 18th century, the government redeemed most of the estate's property. The new main building was built in the 1790s and owned by Wrangel, Clayhills, Bruun and Naht families. Today Kyminkartano is privately owned and not open to the public.
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.
