Oudong is a town in Cambodia, at the base of the Phnom Udong Mountain, northwest of Phnom Penh. It was the site of the royal capital from the 17th to the 19th centuries. The mountain’s two mounds are connected by a ridge and dotted with stupas and shrines dedicated to former kings. Chedi Mouk Pruhm is the burial site of King Monivong. The ruins of the Arthross Temple house a large golden Buddha.
