The Gracar Turn ('Grätzer's Tower') is not recorded in medieval sources, though the historian Valvasor mentions a manor stood on the site in the 14th century, built by the Grätzer family from nearby Gradac, whence its name derives. After passing through numerous hands, it was purchased by Anton Rudež in 1821. The author Janez Trdina was often Rudež's guest at Gracar Turn; several of the former's works were written at the castle, including his best-known, Fables and Tales of the Gorjancers. During World War II part the castle was burned down by partisan fighters. It has since been renovated.
The core of the castle consists of a multi-story residential palacium, surrounded by a rectangular complex anchored by two imposing square towers.
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.
