The Preah Khan is a Buddhist temple built by the Khmer king Jayavarman VII towards 1191 in the north of the city of Angkor Thom, on the site of Angkor to the Kampuchea.

The Preah Kan was a monastic complex Buddhist named Jayaçri ( crowned sword ) in the honor of the victory on the Chams of Jayavarman VII which set it up in 1191. This temple " flat " , much less impressive than the temple-mountains, is surrounded by a first enclosure of approximately 800 m out of 600, itself bordered of ditches of more than 20 m broad. The roadways which cross them, as with Angkor Thom, are decorated balustrades made up of fabulous giants (deva) holding a nāga. Originality, the base of these roadways is carved low-reliefs.

This big space was probably formerly occupied by many dwellings mainly out of wooden. For only witnesses, a lodging of stage on the side of the access road Is and a basin dug in the North-western angle.

In the center, the temple, surrounded by an enclosing wall of 210 m out of 160 m provided at the four cardinal points with important houses with entry of which most complex is that of the East preceded by a large terrace of access. The enclosure of the temple includes/understands many additional buildings including one " room with the danseuses" , of the basins, the " bibliothèques" , of the " cloîtres" inter-connected by galleries which one must cross to reach the enclosure of the sanctuary, itself a dense interlacing of galleries and rooms with colonnades surrounding the turn-sanctuary power station.

The site was used as provisional city during the construction of Ankgor Thom and the monastery was finished after Jayavarman VII settled in its new palate (1190).

It is dedicated to the father of the king builder who is idealized in the form of the Bodhisattva Lokeśrvara. The external wall is decorated with 60 immense garuḍas, guards of the temple.

Close to the temple, in the east small a baray , Jayatatāka, of which the Neak Pean mark the center. It is the set up last baray with Angkor; in front of the fast stranding of these large tanks, the Khmers will build bridge-stopping with a mitigated success.
