Oudong is a town in Cambodia, arranged in the north-western piece of Kampong Speu Province. Situated at the foothill of the mountain Phnom Udong, around 40 km northwest of the cutting edge capital Phnom Penh, Oudong was regal living arrangement and Cambodia's capital for over 250 years until 1866. A momentous illustrious necropolis of sovereigns of a few centuries is scattered on top the unmistakable divided mountain, which keeps running from the southeast toward the upper east. The city's name is gotten from the Sanskrit word "uttuṅga", which means tall, which likely alludes to the mountain. As it had increased religious legitimacy and hugeness it may have experienced expansion towards: "incredible" or "incomparable". Oudong was established by King Srei Soryapor in 1601, after the surrender of Longvek. Under the rule of King Ang Duong (1841-1850), he developed waterways, porches, connects and raised many pagodas in this district. Oudong was later relinquished by King Norodom in 1866 for Phnom Penh.
In 1866, it was relinquished by King Norodom, taking his illustrious court alongside him to the present capital, Phnom Penh. It was broadly harmed by the Khmer Rouge in 1977, alongside alternate sanctuaries, landmarks, and religious structures there. Legend has it that in the Arthaross Temple, the Buddha situated here confronts north rather than the customary course of east, symbolizing a declaration to the quality and energy of the old Khmer kingdom.
In the eighteenth century, local people say, a Chinese head sent his kin out crosswise over Asia to recognize potential dangers. When they came to Oudong, they saw a mountain formed like a naga, with a sinkhole on top of the Arthaross end, and they watched the riches and influence of Khmer society. The Chinese told their ruler that the Khmers were at that point a capable race, and ought to a naga show up through the sinkhole of Arthaross, they would be sufficiently solid to control the world. The Chinese sovereign did not need this, nor did he need a war. Rather, he inquired as to whether he could assemble a sanctuary over the natural hollow, with the Buddha's face towards China so as to ensure his domain. This was named the Arthaross sanctuary, which signifies "eighteen corners", in light of the fact that there are 18 focuses, or corners, incorporated with the sanctuary's structure.
