Kbal Spean

Kbal Spean (Khmer: ក្បាលស្ពាន, Kbal Spéan [kɓaːl spiən]; lit. 'Bridge Head') is an Angkorian-era archaeological site on the southwest slopes of the Kulen Hills to the northeast of Angkor in Banteay Srei District, 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).
