The University of Tartu was established by King Gustavus Adolphus of Sweden in 1632, thus being one of the oldest universities in Northern Europe. Over the centuries it has been closed down, moved to Tallinn and re-opened by Baltic Germans. After Estonia became independent in 1918, the University of Tartu has been an Estonian-language institution since 1919.
The main building of Tartu University is one of the most outstanding examples of classical architecture in Estonia. The main building was built in 1804-1809 according to university architect Johann Wilhelm Krause’s plans. The opening ceremony of the university’s main building took place on 3 July 1809. Since that day, all major university events are celebrated in the Main Hall. Because of superb acoustics many concerts are held here, and its spaciousness allows for conferences to be held. The hall was re-opened on 3 May 2002 following its last renovation
The university’s four museums, its Botanical Gardens, and sports facilities are, by and large, open to the general public. The University possesses some 150 buildings, 30 of which are outside of Tartu. 31 of its buildings decorate the city as architectural monuments. However, the current reforms include attempts to sell, or have the state co-sponsor, several of these buildings and monuments, as well as sports facilities, as they are not seen as part of the university's mission proper. At the same time, there are numerous recently constructed/renovated university buildings and student dormitories, such as the Technology Institute and the Biomedical Center.
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
