Istanbul's Battle Against Fake Heritage Images: What Officials, Experts and Key Figures Are Saying

Digital forgeries are distorting Istanbul's image — literally. Across tourism booking platforms, real estate portals and social media accounts, hundreds of duplicate and artificially generated images purporting to show the city's landmarks have proliferated to the point where municipal authorities and heritage bodies say the problem can no longer be ignored. The Istanbul Metropolitan Municipality's digital services directorate confirmed this spring that it had flagged more than 400 duplicate or manipulated images tied to listed heritage zones in a single audit cycle, prompting calls for a coordinated response.

The timing matters. Turkey's tourism sector posted record arrivals in 2025, with Istanbul receiving upward of 20 million visitors, according to figures cited in the municipality's own promotional materials. With that volume comes an enormous commercial incentive to manufacture compelling visuals — and an equally large risk that travellers, investors and journalists form their understanding of places like Sultanahmet, Karaköy and the Golden Horn waterfront from images that bear little resemblance to physical reality.

What the Institutions Are Saying

KUDEB, the Istanbul Metropolitan Municipality's directorate for the protection of historic structures, has been among the most vocal institutional voices. Specialists there have pointed to a specific pattern: images of Galata Tower and the Süleymaniye Mosque complex are among the most frequently duplicated, often appearing simultaneously on dozens of unrelated commercial listings. The concern is not only aesthetic. Misrepresentation of a protected monument's immediate surroundings can complicate planning applications and distort property valuations in adjacent streets such as Tersane Caddesi and Bankalar Caddesi in Karaköy.

Academics at Istanbul Technical University's faculty of architecture have been pressing the case since at least early 2025 that Turkish cultural heritage registers need a verified digital image library — a single canonical archive against which online representations can be checked. The proposal, which has circulated within the Culture Ministry's digital heritage working group, would assign authenticated reference images to each entry in the national inventory, making it harder for manipulated versions to pass unchallenged on commercial platforms.

Meanwhile, ICOMOS Turkey, the national committee of the international heritage body, raised the issue formally at a workshop held in Beyoğlu in March 2026, where participants examined case studies drawn from the Theodosian Walls corridor and the Balat neighbourhood. Participants noted that duplicate imagery is not a new phenomenon — postcard-era reuse of the same photograph was common — but the scale enabled by generative AI tools represents a qualitative shift. A single manipulated base image can now spawn thousands of variants within hours.

The Commercial Dimension

Real estate is where the stakes are sharpest. Apartment listings in Fatih and Üsküdar have repeatedly appeared on property portals carrying images of views or interiors that do not correspond to the advertised units, according to complaints logged with the Istanbul Chamber of Commerce's consumer advisory service. The chamber has received a growing number of such complaints since 2024, though it has not yet published a full tally. Buyers who travelled from Germany, the Gulf states and the United Kingdom to view properties have in several documented cases found the actual site bore no resemblance to the listing.

The Turkish Competition Authority, known by its Turkish acronym REKABET, has jurisdiction over misleading commercial communications but has so far focused its digital enforcement activity on pricing rather than imagery. Legal specialists at Bilgi University's law faculty have argued in published commentaries that existing consumer protection regulations are broad enough to cover fabricated listing photographs, and that a test case brought before Istanbul's consumer courts could establish useful precedent.

For now, the practical advice from KUDEB and heritage specialists converges on a few concrete steps. Travellers and researchers are urged to cross-reference images against the municipality's own GeoBIM portal, which holds georeferenced photography of major heritage zones updated quarterly. Journalists and editors using stock or user-submitted images of Istanbul sites are advised to verify coordinates and compare against Street View-equivalent records before publication. And property seekers are being told, bluntly, not to make commitments based on listing imagery alone — in-person or notarised video verification before any deposit is the standard the Istanbul Chamber of Commerce is now formally recommending.
