The area around Lauperswil and Rüderswil was originally part of the Freiherrschaft of Signau. By the 12th century it was controlled by the lords of Ruoderswilare, who ruled out of a castle south-west of Rüderswil. By the 13th century this castle was replaced by the new Wartenstein Castle at Lauperswil. It is unknown when this castle was first built, but by 1228 the knight Swaro von Wartenstein lived there. His descendant, Heinrich Swaro, sold the castle in 1284 to Trub monastery, but received the castle back as a fief from the monastery.
By 1288, the castle was owned by Werner von Schweinsberg. The Schweinsberg family also owned land and Attinghausen Castle in the Canton of Uri. Werner's son was the famous Uri Landammann Werner von Attinghausen who signed an early treaty and led Uri during the early years of the Growth of the Old Swiss Confederacy. However, the castle at Wartenstein remained with the Schweinsberg family.
During the Burgdorferkrieg, in 1383, Bernese troops captured and burned the castle. In 1415 the last male heir, Thüring von Schweinsberg, died, leaving the ruins of the castle to his son in law Ulrich von Balmoos. In 1493, the Basel Junker Wilhelm Hug von Sulz inherited the ruins from his grand-children. He built a country manor house in the valley three years later. The castle ruins continued to change hands throughout the following centuries. The Herrschaft of Wartenstein was dissolved and Lauperswil village became part of the Vogtei of Trachselwald.
According to local legend, during the Bernese siege, the last lord of the castle ordered all his treasure thrown down the well. He and his daughter then attempted to flee the castle, but their horse slipped on the narrow trail and they both and the horse fell to their deaths in the valley below.
Drawings from the 19th century show that the main tower was mostly intact at that time, though portions have now collapsed. In 1965 the remaining walls of the inner castle were excavated and repaired.
The heavily weathered castle ruins are located on a wooded hill above the village of Lauperswil. It is about 1 kilometer north-west of the village section of Zollbrück along the Rüderswil road. A steep, about 20 minute, marked trail begins in the hamlet of Blindenbach and leads to the ruins.
The castle was built on a narrow ridge above the village, on three hand carved terraces. The northern terrace may have contained a bailey but that is uncertain. The southern terrace held the main castle with a tower, courtyard and great hall. On the east slope near the castle there are still traces of a building as well as the castle well.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.
