Heritage conservation is often defended in the language of protection. We are told that roofs, shelters, barriers, and “improvements” are necessary to shield fragile monuments from rain, sun, wind, and human contact. Yet the first duty of conservation is not to impose a new idea upon an old site, but to respect the logic of the site itself. The most revealing heritage projects are therefore not always the ones that add the most infrastructure, but the ones that know when to leave a monument alone.
I was recently able to visit the Xixia Imperial Tombs, and what stood out immediately was not only their scale, but their restraint. The mausoleums rise from the landscape without interruption, exposed to the same environment that shaped them centuries ago. There is a sense of confidence in how the site is managed —protection is present, but it does not dominate what you see.
That experience makes the contrast with Ethiopia’s Lalibela rock-hewn churches even more striking. At the Xixia site, the tombs are preserved as part of a vast historical landscape, intentionally left open and protected through management, zoning, and environmental control rather than by covering them. Lalibela, by contrast, has been subjected to large protective structures that were meant to shield the churches from rain but have instead become part of the problem.
The lesson is not that one country values heritage and the other does not. The lesson is that preservation can be misunderstood when it becomes too eager to “fix” what should instead be carefully stabilized, interpreted, and respected in its original form.
The Xixia Imperial Tombs are remarkable not only for what they contain, but for how they are presented. The site is a necropolis of an ancient dynasty, with imperial mausoleums and subordinate tombs spread across a wide desert and mountain environment. Its value is not confined to individual structures; it lies in the relationship between the tombs, the terrain, and the horizon.
Walking through the site, you understand that its openness is not neglect—it is a deliberate conservation choice. The monuments are legible because nothing competes with them visually. The landscape remains intact, and the tombs retain their original context.
That matters because some heritage places lose meaning when they are over-managed. When a site depends on open space, natural light, and environmental context, enclosing it can weaken its historical integrity. Open preservation is a form of discipline: it accepts that authenticity is not improved by covering a monument, but by maintaining the conditions in which it acquired meaning.
Importantly, openness does not mean absence of protection. The Xixia site is carefully managed through environmental controls, flood mitigation, and regulated access. It is protected without being visually rewritten. That distinction is critical.
However, Lalibela presents a more complex challenge. The churches are carved directly into rock, forming a sacred and living landscape that has endured for centuries under natural exposure. Weathering is real, and deterioration is visible. The need for conservation is not in dispute.
What is in dispute is the method.
The large protective structures installed over some of the churches were intended as a solution, but in practice they have introduced new risks. These coverings alter airflow, trap moisture, and disrupt the natural interaction between the rock and its environment. Over time, they are not simply neutral additions—they are actively contributing to the deterioration of the very surfaces they were meant to protect.
This is the uncomfortable reality: not every protective structure protects. In Lalibela’s case, there is growing concern that the shelters are damaging the site, both physically and visually. They impose a foreign architectural layer onto a place whose identity depends on being carved from and open to its surroundings.
The debate is often framed as a question of aesthetics, but that misses the point. The issue is not whether the structures are visually pleasing or not. The issue is whether they are truthful to the nature of the site.
Xixia is a landscape monument; its openness is integral. Lalibela is a rock-hewn sacred city; its exposure is part of its design and meaning. Treating it like a conventional structure that can be covered without consequence ignores its fundamental character.
Authenticity is at stake.
A monument can be physically intact yet conceptually diminished if its relationship to its environment is altered. A shelter that changes how Lalibela breathes, drains, and is experienced does more than protect—it transforms.
Conservation often fails not because of neglect, but because of misplaced action. Institutions feel pressure to produce visible interventions—structures that signal effort and justify funding. These are easy to photograph, easy to present, and easy to defend.
But visibility is not the same as effectiveness.
In many cases, the most responsible conservation measures are the least visible: drainage systems, slope stabilization, careful monitoring, and controlled access. These do not attract attention, but they address the root causes of deterioration.
Once large structures are built, however, they become difficult to question. Too much has been invested—financially and institutionally. As a result, flawed solutions persist, even when evidence suggests they are contributing to the problem.
The value of the Xixia Tombs lies not just in their history, but in the philosophy behind their preservation. The site is treated as an environment rather than a construction challenge. Its integrity is maintained by managing the broader system, not by enclosing individual elements.
Seeing the site firsthand makes this approach more convincing. The tombs do not feel exposed in a vulnerable sense; they feel grounded, stable, and respected. Their preservation is achieved through restraint.
This is a lesson that resonates far beyond China. It shows that intervention is not always the answer, and that sometimes the most effective way to protect a monument is to leave it visible, legible, and connected to its landscape.
What Real Protection Requires
Real conservation begins with humility. It recognizes that monuments are not blank surfaces for technical solutions, but complex entities shaped by environment, history, and meaning.
For Lalibela, this means prioritizing drainage, erosion control, slope management, and careful monitoring of the rock itself. Any intervention should work with the site, not against it. If protective structures are used, they must be minimal, reversible, and demonstrably compatible with the site’s microclimate.
At present, there is a strong argument that the existing coverings fail that test.
For Xixia, the lesson is already clear: protection does not require enclosure. It requires understanding.
Heritage policy must move beyond the reflex that equates protection with construction. Some sites need shelters. Others need distance. Others still need nothing more than careful management.
Lalibela deserves a more thoughtful approach—one that respects its identity as a living, open, rock-hewn landscape. If the structures built to protect it are instead accelerating its deterioration, then the approach must be reconsidered.
The real question is not whether we can cover heritage. It is whether we can protect it without distorting it.
