The Galerian Complex, the most important monumental group in Thessaloniki, was built at the turning-point of two worlds, the Roman and Byzantine. Its erection began in the late 3rd century-early 4th century AD, when the Caesar Galerius Valerianus MaximianusGalerius (260-311) chose Saloniki as the seat of the eastern part of the Roman Empire.

During Early Christian times, important 4th century emperors occasionally stayed in Saloniki due to its significance and geographic location, situated between Rome and the New Rome-Constantinople.

Significant building remains of the complex came to light in excavations carried out during the second half of the 20th century. Some of these, like the Apsidal Hall and the buildings at the archaeological site in Navarinou Square, are visible and open to the public, though most have been buried due to the reconstruction of the historic city center.

In 2008, the archaeological site received an award from the European Union and Europa Nostra for the exceptional and exemplary restoration and conservation of its ruins, as well as the totality of interventions which transformed an abandoned site into a well-organized, educational one which functions as a pole of attraction in the heart of the contemporary city.

The Information Center for the Galerian Complex is located at the archaeological site of the Palace’s Apsidal Hall, at the intersection of Dimitriou Gounari and Alexandrou Svolou Streets. The Center, which has been in operation since October 2015, was designed by the Ephorate of Antiquities, Thessaloniki. It is addressed to visitors to the buildings and building remains of the most important monumental complex in Thessaloniki, whose construction began in the late 3rd-early 4th century AD, i.e. at the turning-point from the pagan to Christian world.

The Center offers a number of services including an exhibition of supporting material, video, interactive applications and chiefly, digital reconstructions of the Complex’s most important buildings—the Rotunda, the Triumphal Arch of Galerius, the Hippodrome, and the Palace of Galerius, remains of which are preserved in Navarinou Square. Thus for the first time the general public will have the opportunity to understand the architectural form of the buildings, to tour their luxuriously-decorated interiors, and to obtain a fuller picture of urban planning in the southeast area of ancient Thessaloniki during the Early Byzantine period.

Parallel to the interactive applications and website of the Galerian Complex, users can learn about the monument’s excavation and leading excavators, as well as the restoration work to its ruins and buildings. The app is accessible from browsers on both fixed and mobile devices regardless of platform.
