Prasat Tam is considered the central temple complex of Koh Ker, the short-lived 10th-century Khmer capital in what is now northern Cambodia. Visitors today encounter sprawling sandstone and brick structures in various states of collapse, their walls draped in jungle vegetation as the surrounding forest steadily reclaims the stonework. The complex once housed monumental sculptures, including a reportedly 15-foot multi-armed Dancing Shiva, and was ringed by a moat that formed part of the city's ancient water-management infrastructure. Much of what stood here is now absent — removed by decades of systematic looting that, according to witnesses Gates met on camera, left some of the most significant pieces shattered or submerged. Gates traveled to Prasat Tam in Season 12 of Expedition Unknown to meet a former looter who could speak firsthand to the scale of what was taken and destroyed.

Lawyer Brad Gordon, who appears on camera with Gates at Prasat Tam, has devoted significant effort to documenting the looting of Koh Ker and building relationships with former participants. His recruitment of Blue Tiger — described in the episode as a member of Cambodia's most prolific smuggling ring — represents the kind of painstaking, years-long trust-building that formal archaeological investigations rarely attempt. Gordon's work, as shown in the episode, focuses on gathering testimony that could help locate missing artifacts and understand the full scope of what was lost.
The broader context of Koh Ker looting is grim. Estimates cited in the episode suggest that organized gangs stole hundreds or even thousands of sculptures from the site during and after the Khmer Rouge era. The regime itself bears indirect responsibility: by denying education to impoverished children and forcing them into military service, it created the conditions in which many former child soldiers later turned to looting as a means of survival. Prasat Tam, as the heart of the complex, was among the hardest hit.
The fate of the Dancing Shiva statue — reportedly a 15-foot multi-armed figure — is one of the more striking claims explored in the episode. The allegation that it was dynamited by looters hunting for hidden treasure beneath it, with fragments allegedly thrown into the moat, reflects a pattern seen at other Khmer sites where the search for valuables caused irreversible destruction to the sculptures themselves. Whether fragments survive in the moat remains, based on the episode, an open question rather than a confirmed finding.
No Wikipedia data was available for this site, so all historical dates and dimensions should be treated as approximate, drawn from the existing site record and episode evidence. Koh Ker's broader significance as a briefly flourishing Khmer capital — and the scale of what Prasat Tam may once have contained — makes the looting documented here a genuine loss for the archaeological record, whatever the final accounting of missing objects turns out to be.
Brad Gordon told Gates that Prasat Tam is 'the heart of the city of Koh Ker' — the Khmer capital that briefly rivaled Angkor in the 10th century.
Blue Tiger, the former looter Gates met on camera, recalled visiting Prasat Tam as a child around 1963 or 1964 — decades before he became part of an organized looting operation there.
The moat surrounding Prasat Tam served an ancient water-management function but is believed to have later been used by looters to conceal toppled or destroyed statues.
Gates was cautioned on camera to watch his step at Prasat Tam, with Brad Gordon noting that sections of the temple are actively 'disassembling' as the jungle reclaims the brick structure.
Prasat Tam is located within the Koh Ker archaeological zone in Preah Vihear Province, Cambodia, and is generally accessible to visitors as part of guided or independent tours of the broader Koh Ker complex. The site's condition is fragile — as Brad Gordon cautions Gates on camera, sections are actively disassembling — so visitors should exercise care and stick to marked paths where available. Check current local advisories and entry requirements before visiting, as access conditions in remote Cambodian archaeological zones can change.
Siem Reap is the nearest major city, approximately 120 kilometers to the southwest — roughly a 2-3 hour drive depending on road conditions.
The dry season, roughly November through April, is generally considered the most practical time to visit Koh Ker, when roads are more navigable and the heat is somewhat more manageable. The wet season brings lush jungle growth that can be visually dramatic but makes travel to remote sites more difficult.
Cambodia National Museum, Phnom Penh
The Cambodia National Museum in Phnom Penh houses recovered Khmer artifacts and is directly connected to ongoing repatriation efforts for looted sculptures from sites like Prasat Tam.
Guatemala Snake King Archaeological Sites
The Guatemala Snake King sites represent a parallel investigation by Gates into a sophisticated ancient civilization whose archaeological record was similarly disrupted by looting and jungle encroachment.
Mexico Mayan Sites
Mexico's Mayan sites share a comparable story of monumental pre-modern civilizations whose religious complexes were abandoned, partially looted, and are now being reclaimed by jungle — a theme central to the Koh Ker episode.
