Sanctuary of Artemis

After the East Baths, the sanctuary of Artemis is the largest monument in Gerasa. A temple stands inside the large courtyard that measures 115 by 155 meters and is surrounded by porticoes on all four sides.

There is no proof at the sanctuary or temple that this was a sacred place or one of worship prior to 135 AD when planning began for this structure. It is likely that the sanctuary was constructed on the site of an earlier necropolis on the orders of Hadrian. Abandoned from the mid-5th century, it was turned into a quarry and was occupied by potters during the Umayyad epoch.
