Schönecken Castle is a ruined hill above the village of Schönecken in the Nims valley in the West Eifel mountains. The castle stands on the lowest hill ridge in the middle of a valley bowl. The site is guarded on all sides by higher hills. The castle was built around 1230.
The castle occupies a 120-metre-long rectangular site with an enceinte and three projecting towers. In the east the site is guarded by a wide neck ditch. The three towers stand on the south side, two of them being still three storeys high. The two round towers probably date to the 13th or 14th century, the central, rectangular one is more recent. All three towers and their curtain walls have been part of a multi-storey residential building since no later than the 16th century, as depicted in an 18th-century painting.
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.
