Hadrian was responsible for the completion of the Temple of Olympian Zeus. To immortalize him, a giant sculpture of the Roman emperor was crafted from ivory and gold (a chryselephantine statue). Also in the temple was an equally remarkable statue of Zeus. The emperor was further honored in 132 AD with this 59 foot triumphal arch. The gateway into the Temple of Olympian Zeus was crafted from Pentelic marble. The arch was also the demarcation for Hadrianopolis, a new section of the city developed by Hadrian.
