(Sremska Mitrovica) Yugoslavia.
The modern city covers the site of Sirmium on the Sava
river, ca. 76 km W of Belgrade (Singidunum). The Roman town was founded in the late 1st c. B.C. on the site
of an earlier Pannonian settlement. It is mentioned first
in history in accounts of the Pannonian-Dalmatian rebellion of the 1st c. A.D. It became a colony under the Flavian emperors and remained for centuries one of the most important cities on the Danubian frontier. It was frequently the headquarters for military operations and was
visited by the emperors Trajan, Marcus Aurelius, Septimius Severus, Maximinus, and Gallienus. Four emperors of the 3d c. were born in Sirmium or the vicinity: Trajan Decius, Aurelian, Probus, and Maximian.
Sirmium was the residence of the governor of Lower
Pannonia and later was the capital of Illyricum. An important mint was founded here by Constantine I. The city
was an ecclesiastical center and several church councils
were convened here during the 4th c. The Huns destroyed
the city in the mid 5th c. but it was restored to the Byzantine empire in the mid 6th c. Sirmium fell to the Avars after a long siege in 582.
Excavations have revealed a number of ancient monuments and have considerably expanded our knowledge of
the ancient city. Among the more recent discoveries are
a part of the imperial palace (4th c.) and the hippodrome
attached to it. The hippodrome, between 350 and 400 m
in length, was built shortly after 315 and, after one major
rebuilding, fell into disuse before the end of the century.
Parts of the foundations for the seats, a cryptoporticus,
the spina, and the raceway have been found.
Sections of the city wall and two large cemeteries have
been cleared. Near the center of the city the public
horreum (4th c.), a large, rectangular structure with
square piers, and part of the baths of Licinius have been
Artifacts from recent excavations are in the Museum
of Sremska Mitrovica; some earlier finds, including a
mosaic of the late Roman period, are in the Vojvodina
Museum in Novi Sad. The Sremska Museum is built
above a large private dwelling (4th-5th c.) and a mosaic
with geometric patterns is preserved in situ within the
museum courtyard. Frescos from the same dwelling have
been restored and are displayed nearby along with a
Roman ship, numerous inscriptions, and architectural
