The stoa was built during the Roman Emperor Cladius. It was standing alongside the Commemoration Road to the east, when walking to thec entre of the city.
Originally, there was a pavillion with 35 columns in the Ionic style. There were 6 steps between the ground and the platform all along the way. Also, there existed 19 shops to the east of the platform.
During the Seljuk period a bath was built where 18 columns of the Stoa was standing before and 3 of the shops were shifted to the north of the stoa. The site is still under restoration.
