Mamer Castle is the town hall for the commune of Mamer, in south-western Luxembourg. It is made up of four buildings, set in recently landscaped surroundings. At the main entrance, there is a sculpture of Nicolas Frantz, two-time Tour de France winner, and Josy Barthel, Luxembourg's only Olympic gold medallist, both of whom were born in Mamer.
A castle was originally built in Mamer in the 10th century. By the French Revolutionary Wars, it had fallen into ruin, and was seized and sold off by the occupying French forces in 1798 to Thierry de Bastogne. Police chief Frederic François built a new castle on the site in 1830, surrounded by a 2-metre high wall. It passed hands to Jacques Fischer and Julie Kremer in 1934.
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.
