This long platform, almost 300 meters (about 1000 feet) long along the west edge of the Royal Square, was used as a viewing place for the royal party and dignitaries to watch public spectacles and processions. It was built at the end of the 12th century (under Jayavarman VII's reign) and modified later in the late 13th century (under Jayavarman VIII's reign). The Terrace of Elephans contains huge reliefs of elephants carved along the walls give it its present name, although there are also reliefs of Garudas, Apsaras, and other mythical creatures. The stepped platform is accessed by stairways, flanked by guardian lions, which project into the Royal Square.
