Arch of Marcus Aurelius
The Arch of Marcus Aurelius was once part of the Ancient Roman city Oea, which was founded by the Phoenicians in the 7th century BC, and later conquered by the Romans. It commemorates the victories of Lucius Verus, the brother of the Emperor Marcus Aurelius, over the Parthians in the Roman–Parthian War of 161–66. The arch is well-preserved and is the sole remaining structure from Roman era-Oea. It can be seen today in modern day Tripoli.
