The Gate of Spalen (Spalentor) is a former city gate in the ancient city walls of Basel. One of the three remaining gateways, it is regarded as one of the most beautiful gates of Switzerland.
In October 1356, a major earthquake destroyed the old Basel. Then local people surrounded their newly built city with a high city wall and a moat in front of it. The ring wall had over 40 towers and seven of them were gate towers like the Spalentor (completed in 1473-74).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.
