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.
Hochosterwitz Castle is considered to be one of Austria's most impressive medieval castles. The rock castle is one of the state's landmarks and a major tourist attraction.
The site was first mentioned in an 860 deed issued by King Louis the German of East Francia, donating several of his properties in the former Principality of Carantania to the Archdiocese of Salzburg. In the 11th century Archbishop Gebhard of Salzburg ceded the castle to the Dukes of Carinthia from the noble House of Sponheim in return for their support during the Investiture Controversy. The Sponheim dukes bestowed the fiefdom upon the family of Osterwitz, who held the hereditary office of the cup-bearer in 1209.
In the 15th century, the last Carinthian cup-bearer, Georg of Osterwitz was captured in a Turkish invasion and died in 1476 in prison without leaving descendants. So after four centuries, on 30 May 1478, the possession of the castle reverted to Emperor Frederick III of Habsburg.
Over the next 30 years, the castle was badly damaged by numerous Turkish campaigns. On 5 October 1509, Emperor Maximilian I handed the castle as a pledge to Matthäus Lang von Wellenburg, then Bishop of Gurk. Bishop Lang undertook a substantial renovation project for the damaged castle.
About 1541, German king Ferdinand I of Habsburg bestowed Hochosterwitz upon the Carinthian governor Christof Khevenhüller. In 1571, Baron George Khevenhüller acquired the citadel by purchase. He fortified to deal with the threat of Turkish invasions of the region, building an armory and 14 gates between 1570 and 1586. Such massive fortification is considered unique in citadel construction.
Since the 16th century, no major changes have been made to Hochosterwitz. It has also remained in the possession of the Khevenhüller family as requested by the original builder, George Khevenhüller. A marble plaque dating from 1576 in the castle yard documents this request.
A specific feature is the access way to the castle passing through a total of 14 gates, which are particularly prominent owing to the castle's situation in the landscape. Tourists are allowed to walk the 620-metre long pathway through the gates up to the castle; each gate has a diagram of the defense mechanism used to seal that particular gate. The castle rooms hold a collection of prehistoric artifacts, paintings, weapons, and armor, including one set of armor 2.4 metres tall, once worn by Burghauptmann Schenk.
