The first structure on the site of Old Bümpliz Castle was a Burgundian royal estate which was built around 900. Around 1250-1270 a round stone tower was built in the center of the site. This round tower was quite unusual for Bernese castles but may indicate a savoyard influence. Since Peter II of Savoy held authority over Bern at the time, it is likely, but not confirmed, that the round tower was built as a symbol of Savoy's power. The round tower no longer exists, but its location is marked with a cross on the floor of the current restaurant terrace. Shortly after the construction of the tower, the wooden wall was replaced with a stone wall and a half-round tower was added to protect the wall. The round central tower was demolished in the following decades. The growing Bernese power began to force Savoy out of Bümpliz and by the late 13th century, there were Bernese nobles who were naming themselves after their estates in Bümpliz. Under the Bernese nobles, the castle remained unchanged until 1470.
In 1470 Bümpliz village and the castle became part of the lands of the powerful Bernese patrician Erlach family. The castle was rebuilt from a purely defensive structure into an impressive administrative and residential castle. A new gatehouse tower was built, and stands, almost unchanged, today. The supports and structure of the drawbridge over the moat are still visible today.
In the following century, the Old Castle became increasingly old fashioned and uncomfortable. In 1742, Daniel Tschiffely hired Albrecht Stürler to replace the old building with the Neues Schloss Bümpliz. The New Castle was built southwest of the Old Castle. During construction, much of the Old Castle was pulled down or rebuilt.
In 1839 Johann Friedrich Albrecht Tribolet bought the Old and New Castles from Carl von Tavel. He rebuilt the buildings and used them as a private sanatorium for mental patients.
In 1979/80 the Castle was rebuilt. The gate was reopened in the gatehouse, a portion of the moat was excavated and a drawbridge added. The windows were rebuilt in the baroque style and the burned roof was rebuilt as close to original as possible. The north-west wing was rebuilt, while the north-east wing was recreated in concrete and glass. A restaurant opened in the north-east wing, the gatehouse and the courtyard. The rest of the building was converted into the Bümpliz village archives and into meeting rooms or offices.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.
