Only small remains of the castle of Wiprecht of Groitzsch on Burgberg ('Castle Hill') are still visible, but the site has been investigated archeologically and is protected as a historical monument.
The Wiprechtsburg is situated on the northwestern edge of the town of Groitzsch and was one of the largest castle complexes in Saxony around 1100 under Count Wiprecht von Groitzsch. A special feature is the oldest stone building in Saxony, the round chapel built by Wiprecht for his wife (daughter of the Bohemian duke Vratislaw II) based on the Bohemian model.
During the summer months the area is used as an open-air stage for concerts and other events.
From Groitzsch, Wiprecht II fought many of his battles for the right to rule and land and continued to build up his power. The once mighty castle was destroyed in 1306. Only parts of the Romanesque round chapel and a residential tower built around 1080 have survived.
Extensive excavations by archaeologists from 1954 to 1968 uncovered the remains of the residential tower and the round chapel and brought to light valuable findings on the history of the castle.With the completion of the excavations, the design of the entire castle area began. An open-air stage was built in the ruins, a vineyard with more than 500 vines, flower beds and hiking trails along the castle mountain and along the banks of the Schwennigke river. Today, 48 exhibits from the immediate vicinity are on display in one of the stone lapidarium corridors. In the summer months, numerous events take place at Wiprechtsburg Castle, the broadcasting of which reaches beyond national borders, e. g. the summer solstice celebration, open-air concerts, and the annual castle festival, to name but a few.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.
