Preah Khan was built around the same time as Angkor Thom, and like it was conceived as a whole city, though on a smaller scale. It was erected on the site of an important military victory and its outer perimeter is guarded by 72 stone garudas (winged mythological creatures depicted throughout Southeast Asia).
A stupa (a domed structure holding Buddhist relics) and numerous smaller Hindu temples indicate the spiritual mix that Preah Khan embodied. In later years it was renowned as a center of scholarly Buddhism.
The restoration program has left mighty silk-cotton tree roots undisturbed; they make an awe-inspiring sight, appearing to wrestle with the stonework. Elsewhere a two-story, round-columned pavilion of uncertain purpose is a charming, free-standing oddity.
Preah Khan is the northernmost of the regularly-visited sites in Angkor Archeological Park, being 8 miles (13 km) from the center of Siem Reap.
