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.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
