The island of Gaddtarmen (Hauensuoli, The Pike´s Gut) off Hanko forms a natural harbour on a sailing route in the east-west direction. Sailors have made more than 600 carvings on the rocks while awaiting favourable winds. The oldest drawings date from the 15th and 16th centuries. Most of the carvings decpict coats of arms of Swedish and Finnish gentry. Probably the most famous carving was made in 1754 by Field Marshal Augustin Ehrensvärd, the originator of Suomenlinna sea fortress.
The site is a unique document relating to the history of the Baltic Sea. It’s added to the tentative list of Unesco World Heritage Site by the National Board of Antiquities.
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.
