Jerash. Jordan. View from the Cardo Maximus of the monumental North Tetrapylon which dates from the 2nd century AD. In the far background is the North Gate which signals the end of the Cardo. Recently restored, the Northern Tetrapylon was dedicated to the Syrian wife of Emperor Septimus Severus and marks the intersection of the Card Maximus and the North Decumanus. Situated in northern Jordan the expansive Greco-Roman ancient city of Jerash is one of the best-preserved ancient Roman provincial towns in the Mediterranean.
