Behind a statue, ancient vase or centuries-old manuscript displayed in a museum lies a long journey that we rarely see. It begins with excavation and may take an object thousands of kilometres away, involve illicit changes of ownership or end in a return to its homeland after decades of legal proceedings. The movement of cultural property is far more than logistics: it is a multilayered issue connecting history, law, diplomacy, ethics and identity.

What Is Cultural Property, and Why Does It Matter?

In Turkish law, cultural property is defined by Law No. 2863 on the Protection of Cultural and Natural Property, which entered into force in 1983. It encompasses movable and immovable assets above ground, underground or underwater that relate to science, culture, religion and the fine arts in prehistoric and historical periods, or that formed part of social life in those periods and possess distinctive scientific and cultural value.

One of its central provisions treats all archaeological objects within Türkiye—whether known today or still undiscovered—as state property. An object recovered from an ancient city therefore cannot become private property. If it is taken abroad, the state can invoke ownership to demand its return.

Movable and Immovable: Two Worlds, Two Journeys

Understanding this movement first requires a distinction. Immovable cultural property—ancient cities, mounds, mosques, churches, inns and baths—is normally preserved in place. Dam construction, road projects or urban redevelopment can nevertheless require an entire building to be dismantled stone by stone and relocated. The rescue of part of Zeugma before inundation by the Birecik Dam and the relocation of historic structures at Hasankeyf because of the Ilısu Dam project are typical Turkish examples.

Movable cultural property includes coins, statuettes, manuscripts, jewellery, vases and similar objects. Precisely because it is portable, this category is most exposed to smuggling, illegal trade and cross-border movement. It is the main focus of this article.

The Anatomy of Illicit Movement: Smuggling and Illegal Trade

The illicit movement of cultural property should not be treated as ordinary theft. It is organised crime that removes objects from their archaeological context, destroys scientific evidence and fragments cultural memory. As Ministry of Culture and Tourism officials emphasise, it is now regarded as a national security issue; the United Nations Security Council also identifies it as a means of financing terrorism.

An object’s illicit journey often follows a chain: illegal excavation, transfers through small domestic intermediaries, border crossing with false documents or by clandestine routes, reappearance on the international antiquities market with a “clean” identity, and eventual sale at auction or entry into a prestigious museum. Knowledge of its original setting—its archaeological context—almost always disappears. For scholarship, the grave, layer and associated finds from which a vase came are as important as its monetary value. Trafficking destroys that information irreversibly.

International Law Responds: The 1970 UNESCO Convention

After the Second World War, decolonisation enabled newly independent states to bring claims over their cultural heritage onto the international agenda. During the 1950s and 1960s, an expanding antiquities black market fuelled systematic looting of ancient sites, making international regulation urgent.

The response was the Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property, adopted at UNESCO’s sixteenth General Conference, held from 12 October to 14 November 1970. Commonly called the 1970 UNESCO Convention, it marked a turning point and has been accepted by more than 140 states. Türkiye is a party: its Turkish text entered domestic law through publication in Official Gazette No. 17232 on 26 January 1981.

Its most important practical consequence is the prohibition of imports into states parties of objects stolen from museums, religious or public institutions in Türkiye, and the obligation to return such objects. A purchaser’s claim to ownership based on a good-faith acquisition does not prevail; compensation is provided instead. The convention also has an important limitation: it did not establish a clear, directly applicable procedure for returning archaeological objects from illegal excavations that were never recorded. This gap remains a major problem for source countries.

On the convention’s fiftieth anniversary, UNESCO declared 14 November the International Day against Illicit Trafficking in Cultural Property. This symbolic step reflects the issue’s continuing relevance and the global responsibility it entails.

Türkiye’s Restitution Efforts in Numbers

Türkiye has been notably active in pursuing restitution in recent years. Work coordinated by the Department for Combating Illicit Trafficking within the Directorate General of Cultural Heritage and Museums combines scientific research, legal proceedings and diplomacy.

According to Ministry figures, more than 13,000 cultural objects were returned to Türkiye between 2002 and 2025. Over 9,000 came back during 2018–2025, including 180 in 2025 alone. Domestic operations seize more than a million objects annually, predominantly coins, illustrating the scale of the problem.

Recent returns have established significant legal and symbolic precedents. The return from the United States of the bronze Marcus Aurelius statue from Boubon in Burdur was achieved by tracing illicit excavations in the 1960s. A Lydian inscription dated AD 215–216 from the Temple of Apollo Aksyros in Manisa returned from Italy in 2020; the Roman Cybele statue, known as the Mother Goddess, returned from the United States the same year. The bronze Lydian kline dated to 530 BC, taken abroad following illegal excavations at Manisa’s Alahıdır Tumulus in 1979, returned from the Getty Museum. The first official return from Canada, a precedent in international law, and the voluntary return from Bahrain of the manuscript Kitab Şerhu’l-Esma, dated 1268, are further notable examples.

In 2023, cooperation with London’s Victoria and Albert Museum also brought back the Head of Eros removed from the Sidamara Sarcophagus at an ancient site in Karaman 140 years earlier. It was reunited with the main sarcophagus at Istanbul Archaeology Museum. Two fragments joining after 140 years vividly express the symbolic meaning of restitution.

A Two-Way Relationship: Returns from Türkiye

The movement of cultural property is not limited to objects claimed by Türkiye. It also returns objects seized within its territory when scientific evidence establishes that they belong to other countries. According to Ministry data, more than 300 cultural objects have been handed over in the last sixteen years to countries including Iran, Iraq, Kazakhstan, Egypt, Peru and China. This two-way practice shows that restitution is grounded in a universal ethical framework rather than a one-sided assertion of rights.

The Universal Museum Debate and a Changing Paradigm

For years, major Western museums argued that objects belong to humanity’s shared heritage and are best protected in their institutions. The British Museum’s stance on the Parthenon Marbles and the Pergamon Museum’s position on the Pergamon Altar are classic examples. Türkiye’s longstanding requests for the return of the altar and the treasures of Troy have not yet achieved a positive outcome.

The global paradigm has nevertheless begun to shift. The universal museum ideal increasingly gives way to the view that objects should be displayed where they belong. Several factors contribute: modern, well-equipped museums in source countries weaken the claim that Eastern countries cannot protect objects; reckoning with colonial histories gains momentum; and diplomatic pressure encourages voluntary returns. Returns of Nataraja statues to India by the United States, Australia and Britain, Machu Picchu objects to Peru by the United States, and Benin Bronzes looted in 1897 to Nigeria by European countries signal this new phase.

Despite the change, the numerical balance remains unfavourable to source countries. Figures suggesting that more than ninety per cent of African-origin objects lie outside Africa, alongside tens of thousands of Middle Eastern and Turkish objects in the British Museum, show that restitution remains significant yet largely symbolic in the broader picture.

Looking Ahead: Technology, Cooperation and Awareness

Technology plays an increasingly important role in combating illicit movement. Launched in 2023 by Türkiye’s Ministry of Culture and Tourism together with the Presidency of Defence Industries, the Identification Project for the Security of Historical Artefacts aims to give objects unique digital identities to facilitate tracking. AI-assisted monitoring systems also scan museum collections and auction catalogues worldwide to accelerate the identification of suspicious objects.

Technology and law are insufficient on their own, however. Public awareness is fundamental. A farmer handing a discovered coin to a museum, a collector questioning an object’s origin before buying it and a customs officer inspecting a suspicious package are links in the same chain. Protecting cultural property is the shared responsibility of every part of society, not the state alone.

Conclusion

Every kilometre an object travels can mean a kilometre of lost knowledge. Removed from its context, cultural property loses the ability to tell its own story. Its movement therefore concerns not only physical displacement but the preservation of memory, the integrity of history and a people’s relationship with its past.

The return of objects from across Anatolia after years of effort enriches collective memory as well as museum displays. Like the Sidamara Sarcophagus reunited with its missing fragment after 140 years, many objects still far away may one day return to their homelands. This is both a legal process and an obligation owed to history.
