The fullest picture of Cambodia today.
Phnom Penh sits at the confluence of the Mekong, Tonle Sap, and Bassac rivers in central-southern Cambodia. Once known as the “Pearl of Asia,” it is a city of striking contrasts: golden royal palaces and gleaming modern towers, solemn memorials and vibrant street markets, quiet temple courtyards and buzzing riverside promenades.
As the nation’s capital, Phnom Penh offers the fullest picture of Cambodia today — its resilience, its creativity, and its warmth. Whether you are a history traveler, a food lover, a luxury seeker, or a first-time visitor, the capital rewards those who give it more than a quick stopover.
What Phnom Penh is
Phnom Penh is in central-southern Cambodia, at the confluence of the Mekong, Tonle Sap, and Bassac rivers — a location that has made it a trading and political center for centuries. It is both a city and a special administrative municipality, equivalent to a province. The urban core is compact and walkable in the central Riverside and Daun Penh areas, while the wider municipality includes rapidly developing districts like Koh Pich (Diamond Island) and Toul Kork.
According to legend, the city takes its name from Daun Penh, a wealthy widow who discovered four Buddha statues washed up on the riverbank and built a hilltop temple — Wat Phnom — to house them. The name Phnom Penh means “Hill of Penh.” It became the capital of Cambodia in 1434 under King Ponhea Yat, after the decline of Angkor.
Under French rule from 1863, Phnom Penh was transformed into a planned colonial city. Wide boulevards, Art Deco markets, and grand villas earned it the nickname “Pearl of Asia.” In April 1975, the Khmer Rouge seized the city and forcibly evacuated it. Under Pol Pot’s regime (1975–1979), an estimated 1.7 to 2 million Cambodians died. Since the 1990s, Phnom Penh has rebuilt and transformed into a bustling modern capital.
Highlights of Phnom Penh
From royal heritage to the city’s riverside and food scene, these are the experiences that define a visit to Phnom Penh.
The Royal Palace is Phnom Penh’s most iconic landmark — a stunning complex of golden-roofed buildings and manicured gardens that remains the official residence of Cambodia’s King. Within the compound, the Silver Pagoda is named for its floor of over 5,000 silver tiles and houses the Emerald Buddha.
Just north of the Royal Palace, the National Museum is housed in a beautiful terracotta-red building around a tranquil courtyard. Its collection of Khmer sculpture and artifacts is the finest in the world — an essential stop before visiting Angkor.
Once a high school, Tuol Sleng was converted by the Khmer Rouge into a prison and interrogation center. Visitors receive an audio guide with firsthand accounts and can walk through the preserved rooms and galleries, which house thousands of photographs of victims.
About 17 km south of the city, Choeung Ek was the execution site for prisoners from S-21. Its mass graves and memorial stupa filled with skulls make it a gut-wrenching but important experience. Most organized tours pair the two sites together.
The riverside along Sisowath Quay is the city’s most popular gathering spot. In the morning, locals come to exercise. By late afternoon and evening, the area comes alive with families, food vendors, and visitors. A sunset or evening cruise along the Mekong is one of the signature experiences.
The hilltop temple that gave Phnom Penh its name, surrounded by mature trees and resident monkeys. It is a peaceful spot that feels far removed from the city below and is an essential stop for understanding the city’s origins.
