The church sits on foundations dating back to the 3rd century AD, with the current structure completed around 780 AD.
The central dome's Ascension mosaic is considered one of the most important surviving examples of Byzantine monumental art.
During its period as a mosque under Ottoman rule, the mosaics were covered with plaster to comply with Islamic aniconism.
The building suffered significant damage during the Great Thessaloniki Fire of 1917 and required extensive restoration.
Archaeological excavations beneath the narthex revealed early Christian baptismal remnants.
The church's architecture served as a direct prototype for many later churches throughout the Balkan Peninsula.
Its original appearance was designed to demonstrate the power of the Byzantine state in the provincial capital.
The floor of the church is partially composed of colored marble slabs arranged in complex geometric patterns.
The Hagia Sophia of Thessaloniki is an 8th-century Byzantine church modeled after the Hagia Sophia in Constantinople. It is recognized as a UNESCO World Heritage site for its well-preserved Byzantine architecture and significant mosaics. The interior features a central dome adorned with an 11th-century Ascension mosaic. The structure serves as an active Greek Orthodox cathedral and functions as a metropolitan seat. Its current form reflects the period of the iconoclasm, evidenced by the cross in the apse replacing a prior depiction of the Virgin Mary. The building transitioned from a church to a mosque in 1585 and was reconverted to a church in 1912. The structural design follows a cross-in-square plan with a spacious ambulatory.
