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.References:
Medvedgrad is a medieval fortified town located on the south slopes of Medvednica mountain, approximately halfway from the Croatian capital Zagreb to the mountain top Sljeme. For defensive purposes it was built on a hill, Mali Plazur, that is a spur of the main ridge of the mountain that overlooks the city. On a clear day the castle can be seen from far away, especially the high main tower. Below the main tower of the castle is Oltar Domovine (Altar of the homeland) which is dedicated to Croatian soldiers killed in the Croatian War of Independence.
In 1242, Mongols invaded Zagreb. The city was destroyed and burned to the ground. This prompted the building of Medvedgrad. Encouraged by Pope Innocent IV, Philip Türje, bishop of Zagreb, built the fortress between 1249 and 1254. It was later owned by bans of Slavonia. Notable Croatian and Hungarian poet and ban of Slavonia Janus Pannonius (Ivan Česmički) died in the Medvedgrad castle on March 27, 1472.
The last Medvedgrad owners and inhabitants was the Gregorijanec family, who gained possession of Medvedgrad in 1562. In 1574, the walls of Medvedgrad were reinforced, but after the 1590 Neulengbach earthquake, the fortress was heavily damaged and ultimately abandoned. It remained in ruins until the late 20th century, when it was partly restored and now offers a panoramic view of the city from an altitude of over 500 meters.
