Emperor Galerius and Thessaloniki

The Roman period was not an exception to this rule. Having in mind the prosperity of “Thessalonica” during these centuries we can easily understand that Roman rulers like Emperor Galerius soon realized the potential this city had and tried to take advantage of it, acting accordingly…

Having risen in power as one of the Tetrarchy rulers and after his successful campaign against the Persians in 299 AD, Galerius chose Thessaloniki as one of the capitals of the province.

He made extended efforts to further enhance the importance of the city in order to emerge as an administrative center by constructing several buildings some of which were impressively luxurious and decorated in great detail! His ambitious plan was aiming at transforming Thessaloniki into a well-organized administrative center in order to meet the needs of the newly created Roman province!

The Galerius palace complex was the administrative center of the Roman Thessaloniki. During the rule of Galerius the city emerged as a financial and trade center of the wider Roman region.

The Galerius Complex was located in the heart of the Roman Thessaloniki. It was built on a straight axis ranging from the North to the South including buildings like the Rotonda, the Triumphant Arch (Kamara), the Palace, the Octagon and the Hippodrome.

The main area was surrounded by buildings that were incorporating typical Roman architecture of religious or monumental character like the Basilica or the Nymphaeum that was serving religious needs. The Northern section of the complex was connected at the height of Kamara to Via Egnatia, one of the most important trade Routes of the wider Roman region.

The Atrium was surrounded by a magnificent colonnade while the elaborately decorated mosaic floors, the statues and the connected arcades were giving an impression of power and prosperity.

The Octagon located at the Southwest side next to the Basilica was perhaps the most luxurious building of all! It is possible that it was the throne room of the Tetrarch ruler while it was beautifully decorated and several meters higher when compared to the rest architectural elements of the complex.

As a hall, the Palace Complex of Galerius was spreading over an area of 150.000 m2 that today includes Rotonda, Navarino Plaza, the parallel streets and the temple of Agia Sofia to the west! Along with the Roman Forum (Ancient Agora) they were the center of daily life in Roman Thessaloniki!
