The Tudor Museum, also known as Rosport Castle was built in 1892, it was the home of the Luxembourg inventor Henri Tudor. During the German occupation of Luxembourg in the Second World War, the castle was used to accommodate girls assigned to the Reichsarbeitsdient who performed farming and house-keeping work. Around 1957, it became a guest house and, in 1964, the American firm Monsanto converted it into a hotel. However business was not very successful and in 1970, the Commune of Rosport bought the castle for its own administrative offices while continuing to rent out the first-floor apartments to vacationers. In 1972, these were replaced by a holiday home for old people.
After restoration work was completed in 1999, serious consideration was given to opening a museum on the premises. In 1981, the celebrations for Tudor's 100th anniversary had included an exhibition on the development of the lead–acid battery, his principal success. Although the decision to go ahead with the museum was reached in 1995, many difficulties had to be overcome and it was only in May 2009 that the 'Friends of the Henri Tudor Museum' were finally able to open it to the public.
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.
