Below the overpass bridge of the 3rd September road, which is located between the Museum of Byzantine Culture and the Thessaloniki International Fair campus, one can visit an interesting part of the eastern early Christian cemetery. It concerns a nucleus of arch covered Christian graves, organized around a cross shaped MARTYRION (Martyrdom ) which has been attributed to Alexandros of Pydna, who suffered martyrdom during the times of Mixamianos Emperor.

Until today fifty eight graves have been excavated. To the north, in touch with the Martyrdom has been excavated the eastern part of a triaisle CEMETERIAL BASILICA. The rest of the church lies under the neighboring buildings of the Thessaloniki International Fair. Special interest on this Basilica presents the shaping of the Sanctuary with “Kyklion” which is a broad, underground semi-circular corridor with marble inlay on the ground and written decoration on the walls, encircling externally the apse of the Sanctuary. It is probable that this crypt was related to the Martyr’s worship.  

In the center of the Sanctuary, below the space occupied by the Altar, the “Engeneion” (consecration) of the church was found which contained a marble shrine and silver reliquary with a “Christogramme” (Jesus Christ’s symbol) engraved on it. Around it a treasure with coins was found (380 -450 a.d) which consist a time border of the establishment of the Basilica. The Basilica survived until the beginning of the 7th century when it was destroyed by the Avaroslav besiegers of the city.
