Cardo Maximus, situated in Jerash, Jordan, represents one of the most well-preserved remnants of Roman urbanism in the Middle East. The ancient city of Jerash, formerly known as Gerasa, is part of the Decapolis, a group of important Classical cities in the region. The Cardo Maximus is the city's central colonnaded avenue, which historically served as the main thoroughfare and is aligned from north to south. Spanning approximately 800 meters, this grand avenue is characterized by its original paving stones and a collection of towering columns on either side, some still standing with their ornate Corinthian capitals intact. Visitors can walk along the Cardo and imagine the bustling daily life that once took place in the commercial heart of the city. This site also features remarkable ancient architecture, like the North Tetrapylon, which marked the crossroads with the Decumanus Maximus (east-west main street), and intricate public fountains, baths, and city walls. The well-preserved state of Cardo Maximus offers invaluable insights into Roman urban design and the cultural history of Jerash.
