The Oberburg or 'Upper Castle' in Manderscheid is located on a hilltop that was levelled in order to construct the castle. It had, as can still be seen from the ruins, an almost triangular enceinte and a five-story bergfried or fighting tower that has been made accessible again. From the bergfried there is a clear view of the Niederburg or 'Lower Castle', the town of Manderscheid and the countryside of the Lieser valley.
The earliest record of the castle, which is first historically known from the feud over St. Maximin's Abbey in front of Trier between Count Henry the Blind of Namur-Luxembourg and Archbishop Albero of Trier, between 1141 and 1146. The free lords of Manderscheid first appear in 1142 in the list of witnesses in a deed of gift.
In the 14th century, the village of Obermanderscheid gave its name to the Electoral Trier Amt of Manderscheid, which existed until the late 18th century. However, the seat of government was not at the castle, but in the Kellerei of the neighbouring village to which Elector Baldwin had granted town rights in 1332 (according to other sources they were granted by King Louis the Bavarian as one of a number of rights). The local estates of the Elector of Trier formed a sort of bridgehead into the surrounding sovereign territory of Luxembourg. In 1673 the castle, still owned by the Electorate, was finally destroyed by French troops.
Today the ruins of the Oberburg were thoroughly renovated in 1921 by the municipality of Manderscheid, on whose land it stands, and it is open 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.
