Oudong

Oudong (Khmer: ឧដុង្គ; also romanized as Udong or Odong) is a former town of the post-Angkorian period (1618–1863) situated in present-day Phsar Daek Commune, Kampong Speu Province, Cambodia, near the border between Kandal Province and Kampong Chhnang Province. Located at the foothill of the mountain Phnom Oudong, also known as Phnom Preah Reach Troap (Khmer: ភ្នំព្រះរាជ្យទ្រព្យ), about 35 km northwest of the modern capital Phnom Penh via National Road No. 5, Oudong was a royal residence and Cambodia's capital for almost 250 years until 1866. A monumental royal necropolis of sovereigns of several centuries is scattered on top of the prominent bisected mountain, which runs from the southeast to the northeast.
