Ancient Phnom Penh Site to Become Open-Air Museum After Temple Foundation Discovery
A newly excavated archaeological site on the outskirts of Phnom Penh has revealed the brick foundation of an ancient temple, offering further evidence that the area around Cambodia's modern capital was inhabited and culturally significant long before the rise of the Khmer Empire.
Located about 17 kilometres from central Phnom Penh, the site sits in an area undergoing rapid urban development.
The discovery is significant not because archaeologists have uncovered a complete temple, but because the remaining foundation adds another piece to the archaeological record of the Phnom Penh region.

Ancient Temple Foundation Discovered
Excavations at Toul Ang Komnob have exposed a brick foundation measuring approximately 4.5 metres by 5.5 metres.
The site has been monitored by the Ministry of Culture and Fine Arts since 2017, when it was documented as one of 91 archaeological sites in Phnom Penh.
Leng Vitou, director of the ministry's Department of Archaeology, said the ministry formally documented Toul Ang Komnob during its 2017 archaeological work.
The earlier survey identified two intact temples among Phnom Penh's archaeological sites, while another 39 sites were hills containing remains of temple foundations.
The newly excavated foundation therefore forms part of a wider archaeological landscape that has existed alongside the development of modern Phnom Penh.
Only Limited Remains Have Been Found
Despite the discovery of the temple foundation, archaeologists have so far recovered relatively little material from Toul Ang Komnob.
In addition to the brick foundation, the excavation uncovered a moonstone, an ornately carved sandstone slab traditionally placed at the entrance of a temple.
The limited archaeological evidence makes it difficult to establish important details about the original structure.
Researchers currently cannot determine with confidence:
The temple's original shape
Its full size
Its height
The broader layout of the ancient structure
The complete history of the site
Leng Vitou said relatively few significant objects had been found at the site so far.
This means that the excavation has revealed an important physical trace of an ancient structure, but much of its historical context remains unknown.
Urban Development Has Changed the Landscape
Toul Ang Komnob is located in an area that has undergone considerable development.
New construction and settlement have transformed the surrounding landscape, while people have moved onto land around the archaeological site.
According to the report, some ancient objects may also have been removed or relocated over the years.
These changes can make archaeological research more difficult because the original context in which artefacts were deposited may no longer be intact.
For archaeologists, context is important because objects and architectural remains can provide information not only individually but also through their relationship to one another.
The Hill Remains Sacred to Local Residents
Although much of the archaeological history of Toul Ang Komnob remains uncertain, the site continues to have importance for local communities.
Two small tutelary shrines remain at the site and continue to attract residents who regard the hill as sacred.
This means Toul Ang Komnob has both archaeological and continuing local cultural significance.
The site's future preservation therefore involves not only protecting physical remains but also recognising its relationship with the surrounding community.
Another Ancient Site Lies Nearby
Toul Ang Komnob is part of a broader archaeological landscape extending beyond modern Phnom Penh.
Approximately seven kilometres away, in neighbouring Kandal province, stands the relatively well-preserved Srei Krub Leak temple on Prasith Mountain.
The nearby temple provides another indication that the wider Phnom Penh and Kandal area contains archaeological remains connected to earlier periods of Cambodian history.
The discoveries at Toul Ang Komnob add another location to this broader record.
From Archaeological Site to Open-Air Museum
The Ministry of Culture and Fine Arts plans to preserve Toul Ang Komnob and eventually develop the location as an open-air museum.
The concept would allow visitors to see the surviving archaeological remains in their original setting rather than only viewing artefacts inside a conventional museum.
For researchers, preservation could also provide an opportunity to continue studying the site as additional evidence becomes available.
For the public, the location could provide a direct connection to an ancient layer of Phnom Penh's history.
Why Preserving Toul Ang Komnob Matters?
Phnom Penh is undergoing rapid urbanisation, with residential areas, roads and new construction continuing to expand around the capital.
Archaeological sites located within or near growing urban areas can face particular challenges.
Once land is developed, archaeological remains can become difficult to access, document or preserve.
Toul Ang Komnob demonstrates how ancient sites can remain embedded within modern urban landscapes.
The preservation plan could therefore help ensure that the archaeological record survives alongside Phnom Penh's continued development.
Angkor Times Analysis: Protecting Phnom Penh's History Before It Disappears
Toul Ang Komnob is a reminder that Cambodia's archaeological heritage is not limited to the famous monuments of Angkor.
The newly exposed foundation is relatively modest compared with Cambodia's major temple complexes, and the available evidence is currently insufficient to reconstruct the original temple in detail.
Its value instead lies partly in what it tells researchers about the historical landscape surrounding present-day Phnom Penh.
The fact that the site was recorded among Phnom Penh's archaeological locations in 2017 also shows the importance of documenting heritage before urban development changes the surrounding landscape.
The proposed open-air museum could give Toul Ang Komnob a second life: first as an archaeological site for research and preservation, and eventually as an accessible heritage destination for residents and visitors.
However, the source makes clear that many questions remain unanswered. More archaeological evidence would be needed to establish the temple's date, architectural form, original function and relationship with other settlements in the area.
For now, the most important discovery is the survival of the ancient foundation itself.
What Researchers Still Do Not Know?
The discovery provides evidence of an ancient temple structure, but the available findings do not yet answer several important archaeological questions.
Researchers still need more evidence to determine:
When was the temple built?
The supplied report does not establish a precise construction date.
What did the temple look like?
Only part of the brick foundation has been exposed, making reconstruction of the complete structure difficult.
How large was the original temple?
The uncovered foundation measures about 4.5 by 5.5 metres, but the full dimensions of the ancient complex are not known.
What was the temple's function?
The available evidence does not provide enough information to establish the temple's original religious or social function in detail.
What happened to the site's other artefacts?
The report notes that some ancient objects may have been removed or relocated as the surrounding area developed.
