Palmyra Was Destroyed Twice. UNESCO Watched Both Times.

It takes a particular kind of optimism to believe that a designation will stop an artillery shell. The United Nations Educational, Scientific and Cultural Organization has spent seventy-three years perfecting this optimism. The formula is elegant: identify a place of universal value, convene experts in Paris, inscribe it on a list, issue a certificate suitable for framing. Then wait for human nature to improve.

On May 21, 2015, fighters from the Islamic State of Iraq and Syria entered Palmyra, a Roman city in the Syrian desert that had stood for two millennia. They held it for ten months. When they withdrew in March 2016, the Temple of Bel—built in 32 CE—was rubble. The Arch of Triumph, which had survived earthquakes, erosion, and the collapse of empires, had been dynamited. The theatre where performances had been held since the reign of Septimius Severus was a mass grave.

UNESCO's response was a press release expressing deep concern. In December 2016, ISIS returned. They destroyed more. UNESCO issued another statement. Palmyra had been inscribed on the World Heritage List in 1980. The designation did not include air support.

The Precedent We Keep Repeating

This is not, of course, without precedent. In 1991, during the Croatian War of Independence, Yugoslav People's Army artillery units shelled Dubrovnik's Old City for seven months. The medieval walls, inscribed as a World Heritage Site in 1979, absorbed 650 documented hits. UNESCO sent observers. The shelling continued. By April 1992, fifty-six percent of the Old City's buildings had been damaged. Nine were destroyed entirely.

In August 1992, Serbian forces systematically destroyed the Vijećnica, Sarajevo's National Library, along with an estimated two million books and manuscripts. It had been built during the Austro-Hungarian Empire. It burned for three days. Firefighters attempting to save collections were targeted by snipers positioned in surrounding hills. UNESCO issued a statement condemning the act as a war crime. The library remained ash.

Between March 2001 and March 2012, the Taliban demolished the Buddhas of Bamiyan twice—first with artillery, then with dynamite when the statues proved resilient. They had been carved into a cliff in the sixth century. UNESCO had placed the site on its World Heritage List in 2003, two years after the statues ceased to exist. One admires the thoroughness.

What the Convention Actually Does

The 1972 Convention Concerning the Protection of the World Cultural and Natural Heritage is a masterpiece of aspirational language. It established a list. It created a committee. It mobilized international cooperation for the protection of heritage of outstanding universal value. What it did not create was enforcement authority, funding mechanisms adequate to the task, or consequences for states that permit destruction.

As of May 2026, UNESCO has inscribed 1,157 properties across 167 countries. The agency's total annual budget for the World Heritage Centre—responsible for all of them—is approximately $5.3 million. This is less than the cost of a single Patriot missile battery. The Centre employs sixty-four staff in Paris. The sites they monitor span fifty-three million hectares. The math is unkind.

One is tempted to observe that capacity-building workshops are of limited utility when the capacity in question is being targeted by airstrikes. But this would be ungenerous. UNESCO operates within constraints not of its own making. The agency has no military force. It cannot impose sanctions. It cannot compel member states to protect sites, even sites those states nominated for protection.

The Toolkit, Such As It Is

When a World Heritage Site comes under threat, UNESCO has three instruments at its disposal. First, it can place the site on the List of World Heritage in Danger. This is intended to mobilize international support. What it actually mobilizes is international attention to the fact that support has not arrived. As of April 2026, fifty-six properties are on the Danger List. Seventeen have been there for more than a decade.

Second, the agency can invoke the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict. This treaty, which has 133 state parties, obliges combatants to avoid targeting cultural sites and to take precautions during military operations. The treaty has been invoked in Syria, Yemen, Ukraine, and Gaza. The invocation is carefully worded. It reminds parties of their obligations. It does not mention that the parties often authored the destruction it condemns.

Third, UNESCO can remove sites from the World Heritage List entirely if they have lost the qualities that justified their inscription. This is the nuclear option. It has been used three times. In 2007, the Arabian Oryx Sanctuary in Oman was delisted after the government reduced the protected area by ninety percent to facilitate oil drilling. In 2009, Dresden's Elbe Valley was removed after Germany built a four-lane bridge through it. In 2021, Liverpool's Maritime Mercantile City was delisted following overdevelopment of its waterfront.

Notice what these cases have in common: they involved governments destroying their own heritage through policy, not armies destroying it through war. UNESCO can shame a democracy that builds an ugly bridge. It has no mechanism to stop a militia that sees heritage as the enemy.

The Argument They Haven't Made

There is a defence of UNESCO's approach that no one in Paris is willing to make publicly, though several officials have made it privately. It goes like this: cultural heritage protection was never supposed to stop wars. It was supposed to create a framework that would survive wars, so that when the shooting stopped, there would be international consensus on what mattered and who was responsible for protecting it.

By this logic, the system is working. After Palmyra, UNESCO coordinated $14 million in restoration funding from Italy, Germany, and France. After the destruction of Timbuktu's mausoleums by Ansar Dine militants in 2012, the agency led a reconstruction effort that restored fourteen of sixteen sites by 2016. After the 2015 earthquake in Nepal, UNESCO's technical assistance helped rebuild the Kathmandu Valley's pagodas within four years.

This is, one must admit, a coherent position. It accepts that UNESCO is fundamentally a post-crisis agency. It does not pretend that international law prevents atrocities; it ensures there is a reckoning afterward. The problem is that this argument concedes the central point: when heritage is threatened, UNESCO will document the loss. It will not prevent it.

What Worked Once

There is exactly one case where international intervention saved a World Heritage Site during active conflict: the Suez Crisis of 1956. When Egyptian and Israeli forces clashed near Abu Simbel, UNESCO's first Director-General, Jaime Torres Bodet, proposed relocating the temples before the construction of the Aswan High Dam would flood them. He secured $80 million in funding—$850 million in 2026 dollars—from fifty countries.

Between 1964 and 1968, engineers cut the temples into 1,036 blocks, each weighing up to thirty tonnes, and reassembled them sixty-five metres higher. The operation was completed on schedule. The temples survived. It was UNESCO's greatest triumph. It has never been repeated. The reason is simple: it required both enormous funding and the agreement of the warring parties. Wars since 1956 have provided neither.

The Wars UNESCO Cannot Stop

Since February 2022, at least eighteen World Heritage Sites in Ukraine have sustained damage from Russian missile strikes and artillery. In Odesa, a July 2023 strike destroyed the Transfiguration Cathedral, built in 1794. In Kyiv, the Kyiv-Pechersk Lavra monastery complex—inscribed in 1990—has been hit seventeen times. UNESCO sent a monitoring mission in October 2022. It confirmed the damage. The strikes continued.

In Yemen, the Old City of Sana'a—continuously inhabited for 2,500 years—has been bombed repeatedly since the Saudi-led coalition began airstrikes in March 2015. As of February 2026, at least 127 buildings in the Old City have been destroyed. The coalition, which includes the United Kingdom and the United States as arms suppliers, has not been sanctioned. UNESCO placed Sana'a on the Danger List in 2015. The designation did not include a no-fly zone.

In Gaza, Israeli airstrikes between October 2023 and April 2026 destroyed or severely damaged an estimated 104 heritage sites, including the Great Omari Mosque, the Church of Saint Porphyrius, and the ancient harbor of Anthedon. None were World Heritage Sites—Palestine's only inscribed sites are in the West Bank—but all met UNESCO's criteria for outstanding universal value. The agency issued statements. The bombing continued.

What Could Work, And Why It Won't

There are four reforms that would give UNESCO actual protective capacity. First, create a rapid-response fund of at least $500 million, pre-authorized for emergency evacuations, structural reinforcements, and emergency site security. Current funding requires months of committee deliberation. Heritage does not burn on committee schedules.

Second, authorize peacekeeping forces mandated specifically for heritage protection. The precedent exists: in 2013, French forces in Mali were tasked with securing Timbuktu's manuscripts during Operation Serval. They succeeded. A standing heritage protection unit under UN auspices could be deployed when sites are threatened. No member state has proposed creating one.

Third, make World Heritage destruction grounds for automatic sanctions—not Security Council-approved sanctions, which are subject to veto, but General Assembly-authorized measures that cannot be blocked by permanent members. This would require amending the UN Charter. It will not happen.

Fourth, establish liability for reconstruction costs. When a state or non-state actor destroys a World Heritage Site, make them financially responsible for restoration. The Islamic State no longer exists as a territorial entity, but its leadership's assets could be seized. Russia could be billed for Odesa. Saudi Arabia could pay for Sana'a. None of these bills will be sent.

The Record Since Palmyra

In the eleven years since ISIS entered Palmyra, UNESCO's World Heritage List has grown by 146 sites. The agency held its annual World Heritage Committee meeting in Riyadh in 2023, New Delhi in 2024, and is scheduled to meet in Rome in July 2026. These meetings inscribe new properties, review periodic reports, and adopt carefully worded decisions on sites in danger.

During those eleven years, thirty-two World Heritage Sites have sustained major damage in armed conflicts. UNESCO documented every incident. It issued statements after each one. It placed twenty-one sites on the Danger List. It coordinated reconstruction for nine of them. The pattern is consistent: destruction happens, UNESCO responds, the international community expresses regret, funding arrives years later, restoration begins if the war has ended.

This is not a system designed to fail. It is a system designed for a world where wars are rare, brief, and fought by parties who care about international norms. We do not live in that world. We live in a world where heritage is a target, either because it represents the enemy's identity or because no one will defend it. UNESCO operates as if this is a temporary aberration. The wars suggest otherwise.

The Honest Answer

So what, exactly, is the World Heritage List for? If it does not prevent destruction, if it cannot compel protection, if its main function is to mobilize funding after the fact—what is the point of inscription?

The honest answer is this: the list is a promise that we will remember. It is a declaration that certain places belong not to the state that governs them but to humanity itself. It is a framework for accountability, even when accountability never arrives. It is an assertion that destroying Palmyra or Dubrovnik or Sana'a is not merely a military act but a crime against all of us.

This is not nothing. But it is also not protection. UNESCO has built a cathedral of international law and cooperative norms around cultural heritage. It is an impressive structure. It keeps out the rain. It does not stop the shells.

The question is whether we are content with a system that preserves the memory of heritage but not the heritage itself. Whether we accept that UNESCO's role is to write the eulogy, not prevent the death. Whether we believe that documentation is enough.

The record suggests we do. Since 1972, we have inscribed 1,157 sites. We have armed zero of them. Palmyra was destroyed twice. Both times, we watched. Both times, we took notes. Somewhere in Paris, those notes are filed carefully, ready for the reconstruction that will begin when the war ends. If the war ends.
