House of Theseus is a Roman villa built in the second half of the 2nd century AD over the ruins of earlier houses of the Hellenistic and early Roman periods. It was in use until the 7th century AD. The villa's large size, it consisted of more than 100 rooms, suggests that the building was the residence of the governor of Cyprus.
Many of the rooms and three of the four porticos around the central court are covered with mosaic floors with geometric motifs. Three rooms in the south wing of the building are embellished with mosaic floors with human representations, all belonging to different phases. The oldest one is the mosaic representing Theseus and the Minotaur, dating to the very end of the 3rd or beginning of the 4th century A.D. with obvious later restorations, probably made after the earthquakes of the middle of the 4th century. At the end of the 4th century A.D. a new mosaic depicting Poseidon and Amphitrite was added to a room, which probably served as a bedroom. Finally, at the beginning of the 5th century, a mosaic floor was laid in the reception room, of which only a part is preserved today and depicts Achilles´ first bath.

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.
