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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
