Baelo Claudia is a well preserved Roman city in Andalucia, Spain, founded in the 2nd century BC. The town was important for fish processing. It was also a centre for trade with Roman towns in North Africa.
The life of the inhabitants reached its greatest splendor during the 1st century BC and the 2nd century AD. In the middle of the 2nd century, however, the town declined, probably as a result of a major earthquake which wiped out a large part. In addition to such natural disasters, by the 3rd century, the town was beset by hordes of pirates, both Germanic and Barbary. Although it experienced a slight renaissance later in the century, by the 6th century, the town had been abandoned.
Excavations have revealed the most comprehensive remains of a Roman town in the whole of the Iberian Peninsula, with extremely interesting monuments such as the basilica, theatre, market, and the temple of Isis. Today you can visit the museum, walk around the remains, and admire the scenic location.
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.
