Kbal Spean (Khmer: ក្បាលស្ពាន) ("Bridge Head") is an Angkorian era archaeological site on the southwest slopes of the Kulen Hills to the northeast of Angkor in Banteay srei, Siem Reap Province, Cambodia. It is situated along a 150m stretch of the Stung Kbal Spean River, 25 kilometres (16 mi) from the main Angkor group of monuments, which lie downstream. The site consists of a series of stone rock relief carvings in sandstone formations of the river bed and banks. It is commonly known as the "Valley of a 1000 Lingas" or "The River of a Thousand Lingas". The motifs for stone carvings are mainly myriads of lingams (phallic symbol of Hindu god Shiva), depicted as neatly arranged bumps that cover the surface of a sandstone bed rock, and lingam-yoni designs. There are also various Hindu mythological motifs, including depictions of the gods Shiva, Vishnu, Brahma, Lakshmi, Rama, and Hanuman, as well as animals (cows and frogs).
