Wat Ounalom is a temple located on Sisowath Quay by the riverside near the Royal Palace. As the seat of Cambodia's Mohanikay order, it is the most important Wat in Phnom Penh, and is the center of Cambodian Buddhism.
It was established in 1443 and consists of 44 structures. It was damaged during the Khmer Rouge period but has since been restored. The main complex houses a stupa that contains what is believed to be an eyebrow hair of Buddha.
