English: The Chan Chaya Royal Palace Pavilion of Phnom Penh in Cambodia (Khmer: "Preah Barum Reacha Veak Nei Preah Reacha Nayeak Kampuchea"), is a complex of buildings which is the royal abode of the Kingdom of Cambodia. Its full name in the Khmer language is Preah Barom Reachea Vaeng Chaktomuk. The Kings of Cambodia have occupied it since it was built in 1866, with a period of absence when the country fell into turmoil during and after the reign of the Khmer Rouge.

The palace was started after King Norodom (1860 – 1904) who relocated the royal capital from Oudong to Phnom Penh after the mid-1800s. It was gradually built atop an old citadel called Banteay Kev. It faces towards the East and is situated at the Western bank of four divisions at the Mekong River called Chaktomuk (an allusion to Brahma).

• The establishment of the Royal Palace at Phnom Penh in 1866 is a comparatively recent event in the history of the Khmer and Cambodia. The seat of Khmer power in the region rested at or near Angkor north of the Great Tonle Sap Lake from 802 AD until the early 15th century. After the Khmer court moved from Angkor in the 15th century, it first settled in Phnom Penh which back then named as Krok Chatomok Sirei Monko in 1434 (or 1446) and stayed for some decades, but by 1494 had moved on to Basan, and later Lovek and then Oudong. The capital did not return to Phnom Penh until the 19th century and there is no record or remnants of any Royal Palace in Phnom Penh prior to the 19th century. In 1813, King Ang Chan (1796-1834) constructed Banteay Kev (the 'Crystal Citadel') on the site of the current Royal Palace and stayed there very briefly before moving to Oudong. Banteay Kev was burned in 1834 when the retreating Siamese army razed Phnom Penh. It was not until after the implementation of the French Protectorate in Cambodia in 1863 that the capital was moved from Oudong to Phnom Penh, and the current Royal Palace was founded and constructed here.

• At the time that King Norodom (1860-1904) signed the Treaty of Protection with France in 1863, the capital of Cambodia resided at Oudong, about 45 kilometers northeast of Phnom Penh. Earlier in 1863, a temporary wooden Palace was constructed a bit north of the current Palace site in Phnom Penh. The first Royal Palace to be built at the present location was designed by architect Neak Okhna Tepnimith Mak and constructed by the French Protectorate in 1866. In that same year, King Norodom transferred the Royal court from Oudong to the new Royal Palace in Phnom Penh and the city became the official capital of Cambodia the following year. Over the next decade, several buildings and houses were added, many of which have since been demolished and replaced, including an early Chanchhaya Pavilion and Throne Hall (1870). The Royal court was installed permanently at the new Royal Palace in 1871 and the walls surrounding the grounds were raised in 1873. Many of the buildings of the Royal Palace, particularly of this period, were constructed using traditional Khmer architectural and artistic style but also incorporating significant European features and design as well.
