The Forum Baths are a ruin of a Roman bath complex in Augusta Treverorum, modern-day Trier. The site was converted in the 4th century CE from some older buildings, dated to around the 2nd century CE. The structure encompassed 8364 m2 The bath house utilized the passive heating of the sun, like many Roman baths, and oriented the caldarium and tepidarium to the south, and the frigidarium to the north.
Along with the other bathhouses, the Forum Baths remained in use through the end of the fourth century. But the complex fell out of use during the early fifth century as Trier was repeatedly sacked during the Migration Period.
In the 13th century, the remains of the bath began being used as a quarry for local buildings. In the 17th and 18th centuries, the Capuchin Order built some of the buildings for their monastery over the eastern part of the bathhouse. In 1802, the monastery was dissolved and nine years later, in 1811, the garden was transformed into a cattle market (German: Viehmarkt), from which the ruins get their name.

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.
