In the northeast corner of the Archaeological Park there is a long street strewn with graves from the Greek, Roman and Byzantine periods, which were carved into the limestone cliffs here. Among them there is also the famous 'tomb of Archimedes', which can be recognized easily by its gabled façade. According to legend, the famous mathematician, who died during the Roman siege of Syracuse in 212 BC, is buried here. However, even the Roman writer Cicero noted that Archimedes was buried in front of the gate to Agrigento. The supposed grave of Archimedes is a Roman columbarium from the 1st Century A.D.
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.
