Saalkirche, today a Protestant church, was constructed on a cross‐shaped floor in the 10th century as a further sacral building in the Ingelheim Pfalz. Thus the imperial palace reached its closed U‐shaped form, which had already been foreseen in the Carolingian building concept. In the following centuries the church was constantly remodelled, mainly in the 12th century. Integrated into a monastery in 1345, the church overcame the resettlement of the former Pfalz area, the so‐called ‘Ingelheimer Saal’ to which the name of the church refers. Given up in course of Reformation the building became dilapidated. In 1965 its reconstruction was completed. A small exhibition on the Ottonian period of the Pfalz was opened inside in 2004.
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.
