Krakus Mound is thought to be the resting place of Krakow's mythical founder, the legendary King Krakus. It has the base diameter of 60 metres and the height of 16 metres. Together with nearby Wanda Mound, it is one of Krakow's two prehistoric mounds, and the oldest man-made structure in Krakow. Nearby are also two other non-prehistoric, man-made mounds, Kościuszko Mound, constructed in 1823, and Piłsudski's Mound, completed in 1937.
The age and the original purpose of the mound remain a mystery, although religious and memorial purposes have been ascribed to the mounds. Excavations conducted in mid-1930s revealed that the mound consists of a solid wooden core covered with soil and turf. Some artifacts dating from between the 8th and 10th centuries were found inside, but no human remains or bones were discovered. According to another hypothesis the mound is of Celtic origin and dates from the 2nd-1st century BCE. Mythical origins are also connected to the mound. Krakus is said to have been constructed to honour the death of King Krakus when mourning townspeople filled their sleeves with sand and dirt and brought it to the site of the Krakus Mound to create a mountain that would rule over the rest of the landscape, as King Krakus had. Originally, four smaller mounds ringed the Krakus Mound, but they were demolished in the 19th century to create Krakow's city wall.
Similar to other ancient structures, such as Stonehenge, the Krakus Mound may have been constructed with astronomy in mind. If one stands on the Krakus Mound and looks towards Wanda Mound at sunrise on the morning of Beltane, the second-largest Celtic feast day, one will see the sun rise directly over Wanda Mound.
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.
