Kbal Spean is an Angkorian era site on the southwest slopes of the Kulen Hills, 25 km from the main Angkor complex. It is commonly known as The River of a Thousand Lingas. It consists of a series of stone carvings in and around the Kbal Spean river. The motifs for the stone carvings are roughly three: myriads of lingas, depicted as neatly arranged bumps that cover the surface of a rock; linga - yoni designs; and various Hindu mythological motifs, including depictions of gods and animals.
