Burg Windeck was once an extended castle site, whose dimensions can still be guessed from the current ruins. The previous imposing castle was first mentioned in 1174 as Neu-Windeck. The site was a border fortification of the Count von Berg against the Counts von Sayn (Homberg) and the von Blankenbergs. It was extended a great deal after 1435. Burg Windeck was destroyed during the 30 Years War and in 1672 by the French and was not rebuilt.
It has since been used for its stone. In 1960 the restoration of the ruin began, the palace wall was re-built and the castle keep was secured. Archaeological investigations and preservation work were carried out in the 1980s. Foundations came to light, which made the extraordinary size of the castle visible.
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.
