At the northwest end of Salona’s town limits, subsequently fortified, there is an amphitheatre, which forms part of the town defence system. Its remains are comparatively well-preserved, showing the benefits of the well known reconstruction made by the Danish archaeologist Ejnar Dyggve.
Dyggve considers that the amphitheatre was designed by Roman architects who performed similar tasks elsewhere too, and that it was built in the second half of the second century AD. Today, we can see only the lower parts of its large walls, largely reconstructed in the 1950s. During the Venetian époque, it was intentionally damaged to prevent it from being used by the Turkish units during their war with Venice in the 16th and the 17th centuries. After that, it was used as a quarry from where stone for house building was being taken, like in many other places.
It is believed that it could have accommodated about fifteen thousand, or even more, spectators. In order to enable fast entrance to and evacuation from the auditorium, a double system of communications was designed: radial, as related to the building ellipse, and circular, as related to the levels of the seat rows. Such a system is quite often at large sports’ stadiums of today. Because of its location along the northern and, partly, the western town walls. Its main entrances must have been in the south and the east walls, which is a deviation from the system comprising two entrances in the east – west longitudinal axis. On its northern side, it stood on elevated soil, some of the walls built on marl (still visible) having therefore no foundations, unlike the other sides. On the southern side, and also on parts of the western and eastern sides, it had three floors: two with arcades and the third with rectangular windows.
In the vicinity of the amphitheatre, to its south, there was a cemetery for gladiators killed in the arena. From their epitaphs, we learn their names, origins, homelands and fighting specialities.
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.
