The Château du Haut-Ribeaupierre is one of three castles (with the Château de Saint-Ulrich and the Château du Girsberg) which overlook the municipality of Ribeauvillé. Château du Haut-Ribeaupierre is the oldest of the Ribeaupierre's castles, its existence being known from 1084. It was constructed on an ancient Roman site. Then known as the 'Altenkastel', it was Anselme de Ribeaupierre who took possession of the castle in 1288.
Around 1368, Brunon de Ribeaupierre became owner. Dedicated to a ferocious hatred for the English, he imprisoned Sir John Harleston, who had an imperial safe conduct, in the keep from 1384 to 1387. He was only freed with the payment of a large ransom and after pressure from the Holy Roman Empire. At the end of the 13th century, the castle became a residence of the Ribeaupierres. Another noted prisoner was held in the keep in 1477. Philippe de Croy, Count of Chimay, ally of Charles the Bold, was captured by a Ribeaupierre at Nancy.
Most of the castle today is completely ruined and surrounded by dense vegetation.
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.
