Laos's Newest World Heritage Site Holds Ancient Coffins, War Scars, and an Archaeologist's Lifelong Passion

In the heart of Laos, the limestone towers of Hin Nam No rise like ancient sentinels. This new UNESCO World Heritage site, recognized just last year, is a place where deep time collides with recent history. Australian archaeologist Daniel Davenport navigates its flooded wet-season tracks in a well-worn Land Cruiser, pointing out a landscape shaped over 400 million years—and then reshaped by war.

From 1963 to 1974, US-led bombing campaigns targeted the Ho Chi Minh Trail here, leaving over 130,000 aerial sorties etched into the earth. Today, monsoon rains fill vast bomb craters. Unexploded cluster munitions still litter the forest floor. 'You only have to walk five metres from these roads to find ordnance,' Davenport notes.

But the caves that once sheltered soldiers now guard far older secrets. In Tham Long cave, Davenport shows us log coffins from the 15th century resting near recent Vietnamese incense sticks left for war dead. His brush reveals 500-year-old bronze trade bells that still jingle. 'These caves superimpose a modern wartime heritage over the older archaeological record,' he explains. He believes hundreds of unexplored caves may hold evidence of ancient hominins, from Homo erectus onward.

Davenport, one of only two foreign archaeologists based full-time in Laos, came for a PhD project in 2004 and never left. He now works to preserve sites like the original sandstone quarry for the Angkor-era temple complex Vat Phou, tracing how 11th-century builders moved massive blocks to the Mekong. For him, the region's power lies in these layers—from prehistoric trade and Hindu temples to wartime scars and living Buddhist festivals. 'It's an archaeologist's dream,' he says, a testament to a land where every stone tells more than one story.
