Mysionis was a large ancient town and fortress. It is located 7 km away of town of Targovishte in region Krumovo Kale, on the northern edge of the steep gorge of the river Vrana in Preslav Mountains.
The site dates back to 6th-7th centuries. After excavations there were found remains of fortress walls 3-4 meters in height, remains of a large church, guard and residential buildings. The slopes of the hills were occupied of neighborhoods and in one of them was found a second large Christian church.
In the vicinity were found also marble columns, antique stone objects, Roman pottery, medieval cemeteries and others. Probably Mysionis existed until the end of the 14th century and was destroyed during the Ottoman invasion.
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.
