Bernstein Castle was first mentioned in the 13th century. In 860 the whole region was part of the archbishopric of Salzburg. The village name Rettenbach was not mentioned yet, but the old Slavic name of the nearby hamlet Grodnau is a sign of the existence of a nearby castle, identifiable with castle Bernstein.
Since 1199 the castle was part of Hungary. It is not exactly known when the castle was handed over to Frederick II, Duke of Austria, and how long it was his property; but in 1236 Béla IV of Hungary conquered the castle. Some years later (in 1260) he gave it to count Henry II of Güssing.
In 1336 the counts of Güssing and Bernstein were defeated by the Hungarian King Charles Robert of Anjou, and the castle of Bernstein became part of the Hungarian Kingdom. In 1388 the castle was given to the Kanizsai family. In 1482 it became property of Matthias Corvinus of Hungary for a short time; in 1487 Hans von Königsberg received the castle from Emperor Frederick III.
In 1529 the Turks besieged the castle, but they were not able to capture it. Another unsuccessful siege by the Turks followed in 1532. On that occasion the ring of bastions was erected in order to change the castle into a refuge.
In 1604 castle Bernstein was unsuccessfully besieged for weeks by a combined army consisting of Hungarians, Turks, and Tatars under the leadership of Stephen Bocskay. Due to an explosion of the gunpowder storeroom, in 1617 Ludwig Königsberg ordered the rebuilding of the Gothic inner part of the castle in Baroque style. The keep and towers were eliminated. A short time later (1644) Ehrenreich Christoph Königsberg sold the sovereignty and the castle to Count Ádám Batthyány. In 1864 Gustav Batthyány sell the castle to his manciple Edward O'Egan, whose heirs finally sold the castle to Eduard von Almásy. His family currently owns the castle. In 1953 a part of the castle was turned into a hotel and restaurant.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.
