Bayon stands at the heart of Angkor Thom, the walled city built as a Khmer capital in the late 12th century. Its position is more than a convenient point on a temple map: the sanctuary was conceived within a royal city, among gates, roads, reservoirs and other monuments. The Cambodian heritage authority APSARA dates the temple to the reign of Jayavarman VII and identifies it as a central expression of the Bayon architectural style. Approaching it from the city’s broad stone avenues helps visitors see how the temple belongs to an urban plan.
The temple’s tiered arrangement draws the eye upward from galleries and terraces toward its central sanctuary. Towers carrying large stone faces rise above the upper levels, creating the image most associated with Bayon. Their calm expressions are visible from different angles, but their precise identity and meaning have been interpreted in several ways. It is more careful to describe what the architecture shows and to note that scholarship debates the faces than to reduce them to a single, certain portrait.
