Genovevaburg is a castle standing on the southwestern side of Mayen in the German state of Rhineland-Palatinate. The castle is the symbol of Mayen and has been rebuilt several times since first being destroyed in 1689. Its name comes from a legend, according to which the seats of counts palatine, Siegfried and his wife, Genevieve of Brabant (German: Genoveva), were supposed to be on the same hill in (or above) Mayen. The earliest references linking the legend to this region date to the 17th century. Since when the castle and its bergfried, the so-called Golo Tower (Goloturm), have been linked to the legend is unknown.
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.
