The church ruin at Rokoberget is the remains of a church dedicated to the archangel St. Michael. The church was built of stone and was sited at the top of the Rokoberget hill. St. Michael's church was first mentioned in a papal letter of 1254 and has been a wayside church, but historians disagree about whether the passers-by were pilgrims or Swedes on their way to the market at Hamar. The ruins, which are accessible to the public, are fenced in. A path down to the right behind the bell tower leads to a look-out point.
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.
