Reuland Castle in Burg-Reuland, near the border of Germany, was probably built after 1148 by the von Reuland nobles. The castle was sold in 1322 to Count John the Blind and the King of Bohemia. On May 24, 1384, King Wenzel of Luxembourg designated Edmund von Engelsdorf the Secretary of the Treasury of Luxembourg, and donated the Castle and the Reuland Domain to him.
The castle's origins can be traced to the 9th and 10th centuries. The entire complex has been modified significantly since then, most importantly to adapt its defences to artillery attacks in the 15th century. Although it was destroyed by French revolutionary troops at the end of the 18th century, it has recently been restored to its former medieval glory.
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.
