Beyond Heracles gate on the right is the Fountain of Trajan. This was built in around 104 CE, it is one of the finest monuments in Ephesus. It was constructed for the honor of Emperor Trajan, and the statue of Trajan stood in the central niche on the facade overlooking the pool.
This monumental fountain on Curetes Street in Ephesus was built by Tiberius Claudius Aristion about 114 CE in honor of Emperor Trajan (98-117 CE) after his visit to Ephesus sometime in 102-104 CE. The statue in the center depicts Trajan as a hero who conquered the world. Other statues in the niches of the fountain were of Aphrodite, Dionysus, and members of the imperial family.
