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 Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
