In the city of Apamea (now Afamia) in western Syria, there are many ruins of an ancient city. There is, among others, the longest ancient street with a colonnade.
The colonnade is almost 2 km long. It was established in the 2nd century CE after the city was heavily damaged in 115 CE by the earthquake. The collonaded street ran north to south – cardo maximus. It was 20.79 meters wide and covered with limestone. The columns were 9 meters high and 90 cm in diameter.
