Phnom Penh is Cambodia's capital and a city of extraordinary historical weight — the seat of the Khmer Empire's royal court, devastated by the Khmer Rouge evacuation in 1975 (when Pol Pot's forces emptied the entire city of 2 million people in 3 days, ordering residents to the countryside where 1.7–2.5 million Cambodians would die from execution, forced labour, disease and starvation over the next 4 years — the worst genocide proportionally of the 20th century, killing 25% of the population), and now a city of 2.5 million undergoing rapid economic transformation driven by garment manufacturing, construction and a growing service sector. The Royal Palace complex (19th century, still the residence of the King) with its Silver Pagoda (the floor is laid with 5,000 silver tiles weighing 90 kg total, and contains a life-size gold Buddha encrusted with 9,584 diamonds) sits on the banks of the Tonlé Sap river at the point where it meets the Mekong — one of the most dramatic urban river confluences in Asia. The Tuol Sleng Genocide Museum (the former S-21 prison where 17,000 Cambodians were interrogated, tortured and executed by the Khmer Rouge — only 12 survived — and the Choeung Ek Genocidal Center (the killing fields, 15 km south) are among the most important human rights memorial sites in the world. Despite — or through — its traumatic 20th century history, Phnom Penh has emerged as one of Southeast Asia's most dynamic cities, with a restaurant and coffee scene that punches far above its weight, the French colonial architecture of the Boulevard Norodom, and the warmth of Cambodian hospitality that has made the country one of the most genuinely welcoming in the region.
The Royal Palace complex (still the residence of King Norodom Sihamoni) has the Throne Hall (Preah Thineang Dheva Vinnichay, 1917), the Royal Residence and the Silver Pagoda — the pagoda floor is 5,000 silver tiles (each 1 kg), containing a life-size solid gold Buddha (90 kg) encrusted with 9,584 diamonds, an emerald Baccarat crystal Buddha and a reclining Buddha of solid gold.

🎫 Book tickets via GetYourGuideFish amok (the national dish of Cambodia — freshwater fish steamed in a banana leaf cup with coconut milk, kroeung herb paste of lemongrass, galangal, turmeric and kaffir lime, and egg for a mousse-like consistency) at a riverside restaurant on Sisowath Quay with the Tonlé Sap river and Royal Palace gardens visible; broken rice with palm sugar dessert.
Wat Phnom (Temple Hill, 1373) is the founding temple of Phnom Penh — legend says a widow named Penh found four Buddha statues floating in the Mekong and built a sanctuary on the hill for them; the 27 m temple mound with its surrounding park, monkeys and the reliquary stupa are the literal origin point of the city; good sunset views over the Mekong.
🎫 Book tickets via GetYourGuideThe confluence where the Tonlé Sap meets the Mekong (the only major river in the world that reverses its flow — running south in dry season and north in flood season, filling the Tonlé Sap Lake to 6x its dry-season size) from a boat at sunset — the wide river, the Cambodian flag on the palace, and the fishing boats create one of Southeast Asia's best urban waterscapes.
🎫 Book tickets via GetYourGuideThe former high school converted by the Khmer Rouge into Security Prison 21 (1975–79) held 17,000 prisoners — only 12 survived; the cells, the interrogation equipment, the prisoner photographs (photographed by Khmer Rouge bureaucrats on arrival — thousands of faces stare from every wall) and the testimonies of the two living survivors (who until recently gave daily testimony) constitute one of the most important human rights sites in the world.
🎫 Book tickets via GetYourGuideThe killing field 15 km south of the city where prisoners from S-21 were trucked at night for execution — the stupa filled with 8,000 skulls, the memorial markers at the mass graves and the audio tour (voices of survivors) at this BAFTA-nominated site; the Buddhist-style memorial was inaugurated in 1988; the site has 129 mass graves of which 86 have been excavated.
🎫 Book tickets via GetYourGuideThe Russian Market (named for the Russians who shopped here in the 1980s Vietnamese-backed government) is Phnom Penh's best market — silk scarves, lacquerware, silverware, kramas (traditional Cambodian scarves), tailored clothing, gemstones and the food section where the local Cambodian workers eat for $1-2; better quality and less tourist pressure than Central Market.
🎫 Book tickets via GetYourGuideStreet 240 (the BKK1 district) is Phnom Penh's most international dining strip — Cambodian tasting menus at Cuisine Wat Damnak (internationally recognized), craft beer at the Hops Craft Beer Garden, or street food at the night market on Street 350; the BKK1 neighborhood has the most concentrated dining in the city.
Koh Dach ("Silk Island", 7 km north, accessible by ferry from the riverfront) is a Mekong island of 10,000 people known for traditional Khmer silk weaving — the looms produce the intricate geometric patterns of Khmer textiles using traditional foot-treadle wooden looms; the island road is car-free and cyclists and motorcycle taxis pass thatched weaving houses and mango orchards.
🎫 Book tickets via GetYourGuideThe Central Market (1937, art deco, largest dome in Southeast Asia at the time) is Phnom Penh's most beautiful building — the yellow domed central hub with four radiating wings covers 4,700 m²; gold jewellery, watches, electronics and dry goods stalls inside the dome; the exterior is the finest French-Khmer art deco in Cambodia.
🎫 Book tickets via GetYourGuideA 3-hour Cambodian cooking class covering the key dishes — fish amok, lok lak (stir-fried beef with Kampot pepper sauce and a fried egg), beef or chicken samlor machu (tamarind soup) and nom banh chok (fermented rice noodles with fish gravy, a Cambodian breakfast staple); Phnom Penh has multiple cooking schools with market tours.
🎫 Book tickets via GetYourGuideThe Sisowath Quay riverside promenade at night with the illuminated Royal Palace and the wide dark river — the tuk-tuks, the floating restaurant boats, the cyclos, the street food vendors selling baguettes (Cambodian French-legacy bánh mì equivalent), and the Cambodian families enjoying the cooling river breeze; a gentle, celebratory end to a city of great weight.
