The village of Holumnica was first mentioned in 1293 and was known for cloth production in the 17th century. Due to lack of historical research, it is not clear which of the stately families (Berzeviczy, Ujhazy, or Görgey) built their castle on the village, but it is estimated to 15th or 16th century. The castle was built in Gothic-Renaissance style and it was inhabited until in 17th century when a mansion in the centre of the village has became the family home. Since then the castle stays abandoned. Nowadays only three ruined walls are to be seen and the stork nestle remains the main attraction.
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.
