Phnom Krom, a hilltop temple 12km southwest of Siem Reap overlooking the Tonlé Sap, dates from the reign of Yasovarman I in the late 9th or early 10th century. The name means ‘Lower Hill’ and is a reference to its geographic location in relation to its sister temples of Phnom Bakheng and Phnom Bok. The three towers, dedicated to Vishnu, Shiva and Brahma, are in a ruined state, but this remains one of the more tranquil spots form which to view sunset, complete with an active wat. The fast boats from Phnom Penh dock near here, but it is not possible to see the temple from beneath the hill.
Oriented toward the east, the temple is enclosed by a wall built of laterite blocks. Along the walls' top runs a cornice. Gates bisect the walls at each of the four cardinal directions. Just inside the east gate are four small buildings arrayed in a north-south row, possibly formerly used as crematoria. Inside the walls on the north and south sides are three halls now collapsed. The temple’s focus is three towers, also in a row running north to south. They sit atop a platform reached by staircases of seven steps. The southern tower is dedicated to Brahma, the central to Shiva, the northern to Vishnu. They are built of sandstone; much of their carving and detail has been lost to erosion.
Phnom Krom is the southernmost of three hilltop temples built in the Angkor region during the reign of Yasovarman. The other two are Phnom Bakheng and Phnom Bok.
