What it is
Hagia Sophia is dedicated to the Holy Wisdom of God, like its namesake in Constantinople. It stands on the remains of an early Christian basilica. The archaeology places it in the seventh century, while the oldest written record of it dates from the late eighth — a hundred years in which the building existed and nobody wrote it down. It is one of the fifteen Paleochristian and Byzantine Monuments of Thessaloniki, inscribed on the UNESCO World Heritage List in 1988.
