In front of the North and South Gates of Angkor Thom (fig.) are naga-bridges, known in Khmer as Spean Neak, that cross the moat and have balustrades displaying the Churning of the Ocean of Milk (fig.) by the devas and the asuras.

The one seen here is the bridge at the South Gate and depicts the western balustrade that shows the gods holding the snake Ananta as a stirring rope (fig.), whereas the railing on the eastern side shows the demons (fig.).
