The Monumental Arch, also called the Arch of Triumph (Arabic: قوس النصر) or the Arch of Septimius Severus, was an ornamental archway in Palmyra, Syria. It was built in the 3rd century during the reign of emperor Septimius Severus. Its ruins later became one of the main attractions of Palmyra until it was officially destroyed by the ISIS in 2015. Most of its stonework still survives and there are plans to rebuild it using anastylosis.
