The foundations of Visingsborg Castle date from 1560s. It was square formed with a moat four towers. The Brahe Family lived in Visingsborg Castle during the 16th and 17th centuries. During their time was one of the most impressive buildings in Sweden. Sculptures and paintings embellished the walls and a large number of books filled the library. The castle also had an armoury that equipped up to 800 soldiers. Outside the walls were large orchards and gardens.The Visingsborg Castle was empty for several years after the death of Count Per Brahe the Younger in 1680. Later, in the early 18th century, it was used as a camp for Russian war prisoners. It is said that it was these prisoners who finally burnt down the castle in 1718. What is left today is only the left wing.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.
