The Église de l′Invention de la Sainte-Croix (Church of the Discovery of the Holy Cross) is the mostly medieval parish church of the small town of Kaysersberg. The church is situated on the Romanesque Road of Alsace thanks to its ornate sandstone portal from ca. 1230-1235.
The Holy Cross Church was built in the first half of the 13th century, then expanded and modified in the 15th century, and finally partially modified again in the first half of the 19th century, when the steeple was crowned with its characteristic dome.
The church is filled with notable artworks, all of which are classified as Monuments historiques. Chief among them are the large wooden polychrome altarpiece of the Passion of Jesus, a 1518 work by the Colmar master Hans Bongart and a large triumphal cross, height 425 cm, from the late 15th century.
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.
