There has been a spa at Alange at least since Roman times when a bathhouse was constructed with separate facilities for men and women. They already existed in the time of Trajan and Adrian, in the 2nd century CE. The Roman building is rectangular and two circular vaulted chambers can be found, one for women and one for men. In the centre of the chambers are the pools, which are also circular. The vaults in the chambers are hemispherical with skylights in the centre. After several centuries of being abandoned, in the 19th century they were refurbished and the current building was built.
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.
