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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
