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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
