Sorginetxe is a funerary monument built around the year 2,500 BC near Salvatierra/Agurain. Here the old ancient inhabitants of the valley, shepherds most of them, used to bury the corpses of their people. It is one of the best preserved megalithic monuments in Euskadi. It consists of five pieces of vertical limestone, some of which reach 2.3 metres.
The place was discovered in 1831 and analysed by Mr. J. Apraiz in 1890, who collected arrow ends and human bones whose whereabouts are not known.

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.
