With its varied façades, the Old City Hall, which was built in 1422 as a merchants’ and excise building, is the jewel of Esslingen. The south face is adorned with ”Allemanisch” timber-framing, while the northern face was extensively modernized during the renaissance, and since then has sported a small, two-story clock tower. Inside the clock tower is a glockenspiel, which was donated by the citizens of Esslingen in 1926 on the occasion of the building’s renovation. The glockenspiel has a repertoire of 200 tunes, which can be heard at various times throughout the day. The preserved original clock mechanism from the astronomical clock of 1591 is among the oldest in Germany. The wings of an eagle, the heraldic emblem of the former imperial city, beat in accordance with the striking of the hour.
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.
