Gornja Radgona Castle was built sometime between 1147 and 1182, and served as an important fortress on the border of Styria with Hungary. The town of Gornja Radgona grew up at the base of the hill upon which the castle is built. The castle is mentioned in 1265 as having 40 subservient villages with 355 farms.
In the late 15th century it was the property of one Hans von Stutenberg, who joined Andreas Baumkircher in a rebellion against Emperor Frederick III. When the rebellion failed, the emperor seized the castle. In 1479 it was occupied by troops loyal to Matthias Corvinus who kept control of the castle until Corvinus' death in 1490. Subsequently it was owned by the emperor but leased to different castellans for a long time. In the late 16th century, it underwent a thorough reconstruction.
In 1623 Emperor Ferdinand II sold the castle to Hans Ulrich von Eggenberg. It remained within the Eggenberg family until 1717, when it befell Leopold, count of Herberstein through marriage. In 1789, he sold it to the count of Wurmbrand and it then stayed in the same family until 1914. In 1931, Slovenian authorities took over the castle itself; it has since served a number of purposes. It was damaged in 1945 during World War II but later repaired. It is today rented out and used as a private residence.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
