Overview
A 5th-century Byzantine basilica dedicated to Saint Demetrius, Thessaloniki's patron, this is Greece's largest church and a UNESCO World Heritage Site. The saint was martyred in a Roman bathhouse here under Emperor Diocletian, and the church was built over his tomb. Restored after the 1917 fire, seven mosaics from the 5th-9th centuries survived the flames as priceless Byzantine art. The crypt below preserves the excavated remains of the ancient bathhouse believed to be the martyrdom site, now open as a museum offering a glimpse of pre-Byzantine Thessaloniki. Free entry (crypt museum about EUR 2). 10-minute walk from Aristotelous Square.
Travel Tips
The crypt has a separate ticket - pair it with the Byzantine mosaics. Avoid visits during mass times.
