The Dolmen de Soto is a Neolithic subterranean structure in Trigueros, Andalucía. It is estimated it was built between 4,500 and 5,000 years ago and is one of about 200 neolithic ritual-burial sites in the province of Huelva.
On the surface it resembles a circle-like mound with a diameter of 75 metres. It has a V-shaped passage 20.9 metres long. In the eastern end of the passage there is a chamber. During the equinox, the first sun lights the interior of the passage and the chamber for some minutes, and it is assumed this was to denote an eventual re-birth of the buried. Several of the standing-stones have engravings, and it is viewed as one of the largest dolmens in Spain. The passage has 31 standing-stones in the northern part of the passage and 33 in the southern part. The standing stones are of quartzite, sandstone, and limestone and carry 20 capstones that make the roof of the passage.
Each of the discovered eight buried bodies were in fetal position and had their respective artifacts beside them. Daggers, cups, and marine fossils were discovered. The artifacts found were not as abundant as those found in other sites; therefore, it is assumed that the Dolmen de Soto was not used for a long time. Engravings were found on 43 standing stones and describe humans, cups, knives, and geometric forms such as simple lines or circles.
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.
