Prasat Krachap is one of the temple complexes within the Koh Ker archaeological site, a remote jungle city in northern Cambodia believed to date to the early 10th century. Built during the reign of the Khmer king Jayavarman IV, the temple is oriented to face west — a detail that, as Cambodian archaeologist Phin Phakdey explained to Gates on camera, directly relates to the Hindu deity Varuna, god of the west and of water, whose image was carved into the entrance pediment. Like many temples at Koh Ker, Prasat Krachap suffered severe looting in the late 20th century, leaving it stripped of major sculptures and partially buried under centuries of jungle debris. What remains is a sandstone structure that offers a fragmentary but vivid window into the religious devotion of a civilization that, according to the episode, ruled over most of Southeast Asia for some 600 years. Gates investigated the site as part of a broader look at Koh Ker's looted heritage and the ongoing effort to identify, track down, and repatriate stolen Khmer art.

On camera, Cambodian archaeologist Phin Phakdey led the excavation at Prasat Krachap and served as Gates' primary guide to the site's history and iconography. Phakdey explained the significance of the Varuna pediment — identifying the seated, cross-legged figure holding what he described as a lasso or rope — and connected the deity's placement to the temple's westward orientation. His commentary framed Koh Ker's short-lived glory as one of the Khmer Empire's most intriguing episodes: a king who moved the capital, built an entire city in the jungle, and then saw it abandoned within roughly 20 years.
Mainstream archaeology generally holds that Koh Ker flourished briefly as the Khmer capital under Jayavarman IV, who ruled in the early 10th century, before the political center shifted back toward Angkor. The site includes dozens of temple complexes and is considered significant for its distinctive artistic style — Koh Ker sculpture is recognizable enough that it is catalogued as its own regional school within Khmer art history. Prasat Krachap is one of the smaller complexes within this sprawling site, but its looting history makes it particularly relevant to the global conversation about illicit antiquities.
The looting of Koh Ker in the late 20th century — amid Cambodia's long period of civil conflict — dispersed major works into private collections and Western museums. Sculptures associated with a Skanda and Shiva group from Koh Ker have been subjects of high-profile repatriation negotiations. The episode's finding that statue foot fragments left in situ can be matched to known looted pieces is consistent with real-world provenance research methods used by archaeologists and law enforcement working on Cambodian repatriation cases, though the specific outcome of any match shown in the episode should be verified through official channels.
What Gates' visit contributed was less a new discovery than a vivid on-the-ground illustration of an ongoing process: active excavation, careful documentation, and the painstaking work of reassembling what was taken or buried. The episode does not claim to have solved the looting crisis, but it puts a human and scientific face on efforts to reclaim Cambodia's cultural heritage — and Phakdey's presence as the lead archaeologist underscores that this work is being driven by Cambodians themselves.
The pediment pieces unearthed at Prasat Krachap had been buried for what archaeologist Phin Phakdey and Gates estimated to be roughly a thousand years before being reassembled on camera.
Varuna, the deity depicted on the temple's recovered pediment, was regarded as both the god of the west and the god of water — a particularly significant patron for Koh Ker, which reportedly lacked a substantial natural water source.
Koh Ker reportedly served as the Khmer capital for only about 20 years before being abandoned, making it one of the shorter-lived imperial capitals in Southeast Asian history.
Koh Ker sculpture is recognized by art historians as a distinct regional style within Khmer art, meaning pieces looted from sites like Prasat Krachap can sometimes be identified by their artistic characteristics alone.
Koh Ker, the broader archaeological site that includes Prasat Krachap, is generally accessible to visitors from Siem Reap, though the remote jungle setting means road conditions and site access can vary seasonally. Visitors should check current advisories with local tour operators, as some areas within Koh Ker have historically required caution due to unexploded ordnance in surrounding areas. An entry fee for the Koh Ker archaeological zone is typically required.
Siem Reap, Cambodia — approximately 120 kilometers southwest of Koh Ker.
The dry season, roughly November through April, is generally considered the most comfortable time to visit, with lower humidity and more navigable jungle roads. The wet season brings lush scenery but can make access to remote temple complexes more difficult.

The Cambodia National Museum in Phnom Penh is the primary repository for Khmer artifacts and is directly connected to the repatriation efforts that the Prasat Krachap excavation informs.
Guatemala Snake King Archaeological Sites
The Guatemala Snake King sites represent a comparable investigation by Gates into a powerful ancient Mesoamerican civilization whose temples and artifacts have also suffered from looting and are now subjects of active archaeological recovery.
