Carrowkeel is a cluster of passage tombs in south County Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic era. Nearby are the Caves of Kesh and Heapstown Cairn. The Carrowkeel tombs are protected National Monuments and are considered one of the 'big four' passage tomb cemeteries in Ireland, along with Carrowmore, Brú na Bóinne and Loughcrew.
The bones curated in Cambridge at the Leverhulme Centre for Human Evolutionary Studies were researched by the Human Population Dynamics at Carrowkeel Project. The original excavation mistakenly dated the monuments as Bronze Age structures, but the new study has shown that the sites were in use between c. 3,500 and 2,500 Cal. BC. Of 22 stable isotope samples, the majority indicated that the dead had grown up in a carboniferous limestone region, probably close to Carrowkeel. The DNA genomes assembled from six individuals indicated ancestral origins in Anatolia, and greater affinity with the Mediterranean than the Danubian expansion of early farming in Europe.
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.
