There was a monumental quadriga at its top with 4 bronze elephant statues.
Erected by the late Roman emperor Theodosius in 380 AD, the Porta Aurea (Golden Gate) was the main ceremonial entrance gate of the land walls of Constantinople, through which the emperors left for their campaigns, and where they celebrated their triumphant return.
In contrast to the usual brick and limestone construction of the city walls, it was built from white marble and had golden doors.
Yedikule Castle was built right next to the Porta Aurea in order to protect the city's main entrance gate (there were 54 other entrance gates along the Walls of Constantinople) from attacks.
