The Collegiate Church (Stiftskirche) towers over the town of Herrenberg, dominating the cityscape. It was built in two main phases of construction (1276-1293 and 1471-1493) and was the first Gothic hall church to be completed in Württemberg. In 1749 the two Gothic towers were demolished and replaced by the Baroque onion dome.
Among the church's outstanding features are the baptismal font from 1472, the stone pulpit from 1504 by Master Hanselmann and the choirstalls from the year 1517 with carvings by Heinrich Schickhardt, the grandfather of the famous architect. The high altar dating from 1519, with paintings by Jerg Ratgeb, is now to be found in the State Gallery in Stuttgart. The Stiftskirche is home to the Herrenberg Bell Museum – and it also boasts the oldest rose window in Swabia.
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.
