A gallery is a passageway running along the wall of an enclosure or along the axis of a temple, often open to one or both sides. Historically, the form of the gallery evolved during the 10th century from the increasingly long hallways which had earlier been used to surround the central sanctuary of a temple. During the period of [[Angkor Wat]] in the first half of the 12th century, additional half galleries on one side were introduced to [[buttress]] the structure of the temple.
