What was the architecture of the Hagia Sophia in Edessa?

The Basilica of Hagia Sophia in Edessa was an ancient Early Christian church rebuilt by Justinian I after a 525 flood. Considered a twin basilica to Constantinople's Hagia Sophia, its architecture featured a single dome rising from a square base, white marble interiors, and surrounding water. Today, hardly any archaeological traces remain, meaning its design must be reconstructed using textual sources like Syriac hymns.

What we know

• The Hagia Sophia in Edessa was constructed in the early 3rd century, destroyed by a flood in 525, and subsequently restored as a Byzantine basilica by Emperor Justinian I. [2]
• The building featured a single dome rising from a square base, and Emperor Justinian I's ambitious building programs during his reign also yielded works such as the Hagia Sophia in the capital. [2, 3]
• The interior of the basilica was predominantly decorated with white marble, reflecting the cultural transformations and public architecture typical of late antiquity. [2, 5]
• Because hardly any archaeological traces remain, textual sources such as a detailed Syriac hymn are used to reconstruct the church's architecture. [2]

Still open

• Travelers and sources differed during the Early Middle Ages, with some Christian and Muslim travelers considering it one of the wonders of the world.
