Top 10 Archaeological Sites in Cambodia
The Khmer Empire, which dominated mainland Southeast Asia from roughly the ninth to the fifteenth century CE, left a monumental landscape centred on the Angkor plain in northern Cambodia that is without parallel in the region. The Angkor Archaeological Park, a UNESCO World Heritage Site since 1992, holds dozens of significant temples and hydraulic structures within a managed area of 400 square kilometres. Beyond it, more Khmer sites extend across Cambodia and into modern Thailand and Vietnam. The Apsara Authority manages access and conservation at Angkor; a single multi-day pass covers most sites.
1. Angkor Wat, Siem Reap Province
The largest religious monument ever built, constructed under Suryavarman II in the first half of the twelfth century CE and dedicated to Vishnu before being converted to Theravada Buddhism. The five towers represent Mount Meru; the moat is the cosmic ocean. Its outer gallery carries 800 metres of bas-reliefs depicting the Churning of the Ocean of Milk, the Battle of Kurukshetra, and Suryavarman's army. Entry is from the west — unusual for a Hindu temple and interpreted as a funerary orientation. Dawn access from the western causeway, with the towers reflected in the moat, is the canonical Angkor image; arrive before 5:30 AM to precede the crowds.
2. Angkor Thom and the Bayon, Siem Reap Province
The walled royal city of Angkor Thom, founded by Jayavarman VII in the late twelfth century CE, encloses nine square kilometres with five monumental gateways flanked by rows of devas and asuras pulling a serpent. The Bayon, its central state temple, is distinguished by 54 towers each carrying between one and four massive carved faces — identified as either Jayavarman himself or the bodhisattva Lokesvara. The galleries carry bas-reliefs showing military campaigns against the Cham and scenes of everyday Khmer life. The Bayon is often best visited in the afternoon when the western light models the stone faces.
3. Ta Prohm, Siem Reap Province
Built by Jayavarman VII around 1186 CE as a Buddhist monastery and university, Ta Prohm was partially cleared but deliberately left with strangler figs and silk cotton trees growing through and over its galleries — a decision by the conservators of the Ecole Francaise d'Extreme-Orient to leave visible evidence of the centuries of forest reclamation. The site accommodated, according to its foundation stele, nearly 80,000 people. The combination of carved sandstone and root systems has made it one of the most photographed temples in the park, but the root systems are structurally compromising the buildings, and conservation work is ongoing.
4. Banteay Srei, Siem Reap Province
A small tenth-century CE temple 25 km north of Angkor Thom, dedicated to Shiva and built in pink sandstone that permits a fineness of carving unmatched elsewhere at Angkor. The pediments and lintels carry scenes from the Ramayana and Mahabharata in relief of extraordinary precision. Banteay Srei was controversially partially dismantled in 1923 by the writer Andre Malraux, who attempted to remove carved sections to sell in Paris — he was arrested and the stones returned. Most visitors come as a day trip from Siem Reap.
5. Preah Khan, Siem Reap Province
Another of Jayavarman VII's major foundations, built in 1191 CE as a temple city and Buddhist university. Preah Khan covers 56 hectares and was once home to nearly 100,000 priests, dancers, and servants. Unlike Angkor Wat, it has been only partially cleared; collapsed galleries and root-draped gopuras give it a more ruined character than its neighbours. A Hall of Dancers with false windows and apsara carvings along its facade is the most visited section.
6. Beng Mealea, Siem Reap Province
A large twelfth-century CE temple 40 km east of Angkor Thom and roughly contemporaneous with Angkor Wat. Built in laterite and sandstone on a similar cruciform plan to Angkor Wat but never cleared, Beng Mealea is genuinely ruinous — collapsed blocks, intact pools, and narrow wooden walkways threading through the debris. The site receives a fraction of Angkor's visitor numbers and gives a clear picture of what the major temples looked like before conservation intervention.
7. Koh Ker, Preah Vihear Province
The short-lived capital of the Khmer Empire under Jayavarman IV, who ruled from Koh Ker between 921 and 944 CE. The site covers 81 square kilometres and includes Prasat Thom, a seven-tiered sandstone pyramid 35 metres high — the only substantial pyramid in the Khmer architectural tradition. Koh Ker was listed as a UNESCO World Heritage Site in 2023. It is 120 km from Siem Reap, making it a full-day trip; access roads have improved significantly in recent years.
8. Phnom Bakheng, Siem Reap Province
A late ninth to early tenth century CE temple mountain constructed by Yasovarman I on a natural hill overlooking the Angkor plain. Phnom Bakheng was the first state temple in what became the Angkor complex, with 108 towers symbolising the astronomical calendar. Its popularity as a sunset viewpoint has subjected it to severe visitor pressure; the Apsara Authority caps the number of visitors on the hill at any one time. The view of Angkor Wat at sunset from the summit is genuinely striking, but arrive early for a place.
9. Phnom Kulen, Siem Reap Province
A sandstone plateau 50 km northeast of Siem Reap, regarded as the sacred heartland of the Khmer Empire: it was here that Jayavarman II proclaimed himself devaraja (god-king) in 802 CE, founding the Angkor imperial tradition. The river at Phnom Kulen carries a bed of carved lingas — Shiva's symbol — so that the water flowing downstream to Angkor was consecrated. A large reclining Buddha carved in the twelfth century CE from a natural rock face is the main visitor focus. The plateau is a Cambodian national park.
10. Sambor Prei Kuk, Kampong Thom Province
A pre-Angkorian site 30 km north of Kampong Thom city, the capital of the Chenla Empire under Isanavarman I in the early seventh century CE. Sambor Prei Kuk represents the immediate architectural antecedent of the Angkor tradition and became a UNESCO World Heritage Site in 2017. Three principal temple groups in laterite and brick survive in varying states of preservation. The site is less visited than Angkor and gives a clear picture of the Khmer tradition at an earlier and less ornate stage.
Planning your visit
The Apsara Authority pass covers most Angkor-area sites and is available for one, three, or seven days; buy it at the official ticket office on the road from Siem Reap before you reach the first checkpoint. Dawn visits require arriving at the Angkor Wat moat by 5:15 AM; tuk-tuks from Siem Reap run from around 4:30 AM. The hottest months are March to May — the November to February dry season is the most comfortable for walking. Every site on this list is marked on the map; several require a day-trip vehicle or guided tour.
