According to the Syria Central Bureau of Statistics (CBS), Qasr Ibn Wardan had a population of 467 in the 2004 census.

[1] The complex of a palace, church and barracks was erected in the mid-6th century by Byzantine Emperor Justinian I (r. 527–565) as a part of a defensive line (together with Resafa and Halabiye) against the Sassanid Empire.

Its unique style, imported directly from Constantinople and not found anywhere else in present-day Syria, was probably chosen to impress local Bedouin tribes and to consolidate control over them.

Originally, the church was topped by a large dome (only a pendentive remains until today) and displays an example of early Byzantine dome-building techniques.

Originally, three sides of the church (only northern and southern walls remain) had upper floor galleries reserved for women.
