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.
Basalt was brought from areas far north or south from the site and marble columns and capitals are thought to have been brought from
Apamea. Nothing remains of the barracks today. The palace was probably the local governor's residence as well. Its best-preserved part is the southern façade of
alternating bands of basalt black and brick yellow. There are remains of stables in the northern part of the site and a small
bath complex at the eastern part of the palace with a central courtyard. The function of each room was indicated by a carved stone. The church was square-shaped with a central
nave and two side
aisles. Its remains currently stand just west of the palace and is architecturally similar to it, but a slightly smaller. 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. The fourth side is finished by a typical Byzantine semicircular and half-domed
apse. ==Syrian Civil War==
