The Felsenkirche, a church built into a natural niche in the rocks, rises high above the houses of Oberstein. Wyrich IV of Daun-Oberstein had it constructed in the years 1482-1484. Behind it, a wall of rocks rises steeply upwards; and under it, the houses of Oberstein nestle into the slope. On account of its prominent location, the church has become a symbol of the city. It can be entered only through a tunnel which was dug into the rocks.
The church’s greatest treasure is the medieval winged altar. It was created around 1400 by an unknown painter, the “Master of the Mainz Mocking”.
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.
