The 1st floor Naga bridge

Next from the pathway, it is the 1^st level Naga bridge that constructed of sandstone with a cross-sign layout, 8.20 meters wide, 20 meters length raising floor from the pathway about 1.50 meters high. The front and flank parts were demoted, there is the bracket-shaped amphitheater as a stairway. The acclivity in backside is a wide terrace connecting with the stairway to Prasat. The pillar and bridge edge were engraved with a beautiful pattern, the railing created as the 5-headed Naga facing and spreading Pang Parn (hood of a cobra) in four directions. A pattern of Naga spreading a radius is an engraved plate in landscape which is a prominent style of the Khmer art of Angkor Wat which can be defined age around the 17^th century Buddha.

The Naga bridge railing is compared as the rainbow which the ancient people often compare with the colorful snake (Naga) raised their heads to the sky or drinking water from the sea. It is frequently happened for double rainbow that represented to the way to the sky of deity. Therefore, it probably was the inspiration to construct Naga at the bridge railing like the representative of deity way that imitated to the human realm.
