Ballochroy is a megalithic site in Kintyre on the Argyll peninsula. It consists of three vertical stones, side by side, aligned with various land features 11–31 km away.
Alexander Thom, known for his work on Stonehenge, maintained that the great length between the stones and the features of distant landscape lent precision to pinpointing the midsummer and winter solstices for ancient observers.
These three stones are considered the most spectacular set of megalithic monuments that cluster around south Argyll. It is possible that this last, smallest, stone may have been broken off at the top. The line of stones is orientated north-east to south-west.
As with many megalithic sites, the current theories concerning the exact use of the stones at Ballochroy are somewhat controversial.
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.
