Great Colonnade at Palmyra
Palmyra, Syria
The Great Colonnade at Palmyra was the main colonnaded avenue in the ancient city of Palmyra in the Syrian Desert. The colonnade was built in several stages during the second and third century CE and stretched for more than a kilometer (approximately.75 miles). It linked the Temple of Bel, in the southeastern end of the city, to the West Gate and the Funerary Temple in the northwestern part. The colonnade was damaged during the Syrian Civil War, especially when Palmyra was occupied by the Islamic State of Iraq and the Levant from May 2015 to March 2016. However, large parts of it are still intact.
