Church of Saint Demetrius
Make Saint Demetrius the main church stop on a walk through central Thessaloniki. Its scale and location reward more time than a quick look at the smaller Byzantine churches nearby.

Keep exploring Thessaloniki with our travel partners.
Beneath the basilica, the crypt incorporates part of a former Roman bath, physically tying the saint’s church to an earlier city. Surviving mosaics above ground speak to its early Christian life, while devotion to Demetrius gives the building unusual civic weight. These layers make it a defining Thessaloniki monument rather than merely another Byzantine church.
Useful to know
Allow time for the basilica and ask locally whether the crypt is open that day.
