St. Michael's Church with its famous staircase towers majestically over Schwäbisch Hall's marketplace. It was consecrated on 10th February 1156 by the Bishop of Würzburg. From this period only the four bottom storeys of the Romanesque west tower have survived, along with the porch. From here the Archangel Michael – a stone sculpture from the late 13th century – watches over the trading on the marketplace and over the town as the guardian of justice. Outstanding works of Late Gothic art in the church interior include the large Netherlandish Passion Altar in the choir (c. 1460) and the Holy Sepulchre with its impressive mourners (1455/56).
From the marketplace the 53 steps of the vast staircase lead up to the Romanesque vestibule of the church, and another 160 steps take you up through the tower to the bell chambers and the former tower watchman's dwelling, which affords a magnificent view over the historic town centre. The staircase was constructed between 1507 and 1510/1511.
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.
