Reuland Castle in Burg-Reuland, near the border of Germany, was probably built after 1148 by the von Reuland nobles. The castle was sold in 1322 to Count John the Blind and the King of Bohemia. On May 24, 1384, King Wenzel of Luxembourg designated Edmund von Engelsdorf the Secretary of the Treasury of Luxembourg, and donated the Castle and the Reuland Domain to him.
The castle's origins can be traced to the 9th and 10th centuries. The entire complex has been modified significantly since then, most importantly to adapt its defences to artillery attacks in the 15th century. Although it was destroyed by French revolutionary troops at the end of the 18th century, it has recently been restored to its former medieval glory.
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.
