At the tip of the Great Northern Peninsula of the island of Newfoundland, the remains of an 11th-century Viking settlement are evidence of the first European presence in North America. The excavated remains of wood-framed peat-turf buildings are similar to those found in Norse Greenland and Iceland.
Dating to around the year 1000 (carbon dating estimate 990-1050 CE), L'Anse aux Meadows is the only site widely accepted as evidence of pre-Columbian trans-oceanic contact. It is notable for its possible connection with the attempted colony of Vinland established by Leif Erikson around the same period or, more broadly, with Norse exploration of the Americas.
Today the area mostly consists of open, grassy lands; but 1000 years ago, there were forests which were beneficial in boat-building, house-building and for iron extraction. The remains of eight buildings were located. They are believed to have been constructed of sod placed over a wooden frame. Based on associated artifacts, the buildings were variously identified as dwellings or workshops.
L'Anse aux Meadows was named a World Heritage site by UNESCO in 1978.
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.
