Once known as the "Pearl of Asia"[2] in the 1920s, Phnom Penh, along with Siem Reap, is a significant global and domestic tourist destination for Cambodia. Phnom Penh is known for its traditional Khmer and French influenced architecture.
Phnom Penh is the wealthiest and most populous city in Cambodia. It is also the commercial, political and cultural hub of Cambodia and is home to more than 1.5 million of Cambodia's population of over 14 million[3].
Phnom Penh was also previously known as Krong Chaktomuk meaning "City of Four Faces". This name refers to the junction where the Mekong, Bassac, and Tonle Sap rivers cross to form an "X" where the capital is situated. Krong Chaktomuk is an abbreviation of its ceremonial name given by King Ponhea Yat which was "Krong Chaktomuk Mongkol Sakal Kampuchea Thipadei Sereythor Inthabot Borei Roth Reach Seima Maha Nokor".
Phnom Penh first became the capital of Cambodia after Ponhea Yat, king of the Khmer Empire, moved the capital from Angkor Thom after it was captured by Siam a few years earlier. There are stupa behind Wat Phnom that house the remains of Ponhea Yat and the royal family as well as the remaining Buddhist statues from the Angkorean era. There is a legend that tells how Phnom Penh was created. In the 1600s, Japanese immigrants settled on the outskirts of Phnom Penh. [4]
It was not until 1866, under the reign of King Norodom I, that Phnom Penh became the permanent seat of government, and the current Royal Palace was built. This marked the beginning of the transformation of what was essentially a riverside village into a city with the French Colonialists expanding the canal system to control the wetlands, filling in lakes, constructing roads and building a port.
By the 1920s, Phnom Penh was known as the Pearl of Asia, and over the next four decades continued to experience growth with the building of a railway to Sihanoukville and the Pochentong International Airport (now Phnom Penh International Airport).
