Brunegg castle was built on a hill at the edge of the Jura mountains in the 13th century. This castle was probably built, together with near Wildegg castle, as part of the Habsburg border defenses. The castle was occupied by Habsburg knights, including Schenken von Brunegg and Gessler von Meienberg. In 1415 the castle was besieged by Bernese troops, but they lifted siege after a counterattack. However, Bern conquered the Aargau, and awarded the fief to the Segenser or Segesser family.
Between 1538-1798, the castle was subordinate to the Governor of Lenzburg. In 1815 it became the property of the Hünerwadel family of Lenzburg. The current owners of the castle, the von Salis family, inherited the castle through marriage from the Hünerwadels. For hundreds of years, the castle was poorly maintained, and in the 17th Century it was heavily damaged twice through storm and tempest. In 1805-06, the keep and out buildings were repaired and the roof was rebuilt.
The village of Brunegg owes its name and existence to the castle. Initially it belonged to the personal land of the Habsburgs. In the 14th Century, they granted the rights to low justice into the hands of the castle owners. Bern placed in the court of Othmarsingen in the Lenzburg district. In the 19th century it was part of the Brugg district though since 1840 it has been in the Lenzburg district.References:
The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
