Sheldon stone circle lies about 200m north of a minor road at Sheldon Farm. There are six large stones still standing, plus an equally large outlier close by at the east. The circle appears to be built on a raised platform, and the outlier stands at the end of a peninsula extension of this platform. The stones do not appear to be height graded, and there is no sign of a recumbent or possible flankers, but there are the remains of what could be a ring cairn in the interior.
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.
