Isfahan

Iranian city; site of nuclear fuel conversion facilities, UNESCO heritage square, and wartime executions.

Isfahan's Dastgerd Prison hanged Mohammad Amini Dehaghani in secret on 15 July; the same silent pattern, no family warning, recurred nationwide on 1 August at Shahrud, as Iran's Hengaw monitor tallied at least 67 executions in July, only eight acknowledged.

Background

Isfahan is Iran's third-largest city, home to around 2.2 million people in the city itself and 5.5 million across the province, some 340 km south of Tehran. Naqsh-e Jahan Square, one of the great public squares of the Islamic world, is a UNESCO World Heritage site, a cultural profile that sits uneasily beside the city's other defining feature.

That feature is the Isfahan Nuclear Technology Centre, which converts uranium ore into the hexafluoride gas used in enrichment. Israeli and American strikes destroyed the centre's surface buildings and sealed its tunnel entrances, and satellite imagery is now the only way to assess what remains inside a hardened underground vault that no IAEA inspector has entered since access was cut off. That lockout has run longer than any prior IAEA access gap on record in Iran.

The province is also a working industrial centre, anchored by Mobarakeh Steel, and its prisons, including Dastgerd, have become a recurring site in the documentation of wartime executions carried out with little or no public trial record.

Key Issues
Wartime executions

Its prison count keeps climbing

Isfahan's Dastgerd Prison hanged Mohammad Amini Dehaghani on 15 July over a January arson charge, with no public record of any trial; his family, like the fifteen uprising convicts hanged there before him, had no warning.

The same silent method resurfaced FAR from Isfahan on 1 August, when Arvin Kheirkhahan was hanged at Shahrud with his family told only to collect the body, a sequence Hengaw says mirrors what happened at Isfahan weeks earlier. Iran's national tally for July reached at least 67 executions, of which the state acknowledged just eight, suggesting Isfahan's opaque prison practice has become the national template rather than a local anomaly.

Nuclear inspection stand-off

Its buried uranium stays unverified

Satellite imagery is the only evidence of what survived under Isfahan's mountain: IAEA director general Rafael Grossi told the Associated Press that roughly 200 kg of Iran's stockpile of 60%-enriched uranium was moved into a hardened tunnel there four days before the June 2025 strikes, and no inspector has set foot inside since.

The stand-off has only hardened since. An 18 June memorandum committed Iran to destroying its uranium stockpile nationwide under IAEA supervision, the same day Khamenei dismissed full access and a stockpile handover as 'excessive demands'. Isfahan's vault, holding nearly half that stockpile, remains as unverifiable months on as it was the day the tunnel was sealed.

Common Questions

Its buried uranium stays unverified

Was Isfahan's nuclear facility destroyed in the Iran war?
The surface facilities at Isfahan's Nuclear Technology Centre were destroyed in June 2025 during the Twelve-Day War (Operation Rising Lion and Midnight Hammer), not in the February 2026 conflict. The underground vault holding roughly 200 kg of 60%-enriched uranium was sealed but not destroyed.Source: IAEA / ISIS five-month assessment

Reference

Is Isfahan the same as Natanz?
No. Natanz is a separate facility roughly 150 km north of Isfahan, known for uranium enrichment centrifuges. Isfahan's Nuclear Technology Centre performs uranium conversion. Both sites had their surface facilities destroyed in June 2025; Fordow near Qom was struck separately by US bunker-busters in the same operation.Source: IAEA
What is the Isfahan Nuclear Technology Centre?
The Isfahan Nuclear Technology Centre (UCF) converts uranium ore into uranium hexafluoride gas for use in centrifuge enrichment. Its surface buildings were destroyed in June 2025; underground storage remains intact but inaccessible to IAEA inspectors.Source: IAEA
How far is Isfahan from Tehran?
Isfahan is approximately 340 km south of Tehran. It is Iran's third-largest city and a major industrial and defence-manufacturing hub, as well as a UNESCO World Heritage site.
Is Isfahan safe from further strikes?
Further military strikes on Isfahan are possible but not confirmed as of June 2026. The city has been struck multiple times: Israeli operations in June 2025 targeted nuclear and defence facilities, US Tomahawks collapsed uranium storage tunnels, and further blasts were reported in June 2026. The underground uranium vault survived all strikes.Source: Lowdown conflict reporting; IAEA monitoring
What happened to protesters in Isfahan during the 2026 war?
Isfahan was an acute site of wartime political repression. In January 2026, residents joined anti-war protests; multiple were charged with moharebeh (waging war against God). Sasan Azadvar, a 21-year-old karate champion, was executed at Isfahan's Dastgerd Prison on 30 April 2026, and Abbas Akbari Feyzabadi was executed in Isfahan province on 25 May 2026.Source: Iran Human Rights (IHRNGO); Lowdown reporting
Why is Isfahan significant in the Iran nuclear deal talks?
Isfahan's underground vault is the most likely location of Iran's 440.9 kg stockpile of 60%-enriched uranium, the central bargaining chip in Ceasefire negotiations. The Islamabad MOU signed 15 June 2026 requires the stockpile to be destroyed under IAEA supervision; Iran's Supreme Leader called that demand excessive and the site remained closed to inspectors as of 23 June.Source: Islamabad MOU; Lowdown reporting, June 2026
Where is Iran's enriched uranium stockpile now?
The IAEA assesses on satellite imagery alone that the 440.9 kg stockpile is likely still at Isfahan's underground vault. Inspectors have had no access since February 2026, and the agency formally declared a loss of continuity of knowledge on 4 June 2026. The underground storage survived the 2025 strikes; US strategy was access-denial rather than destruction of the material.Source: IAEA Board of Governors, June 2026; IAEA Director General Grossi
Is Naqsh-e Jahan Square in Isfahan damaged?
The UNESCO World Heritage site itself was not directly struck. Strikes hit military depots and the nuclear complex on the outskirts of the city; a civilian refrigerator factory was hit on 14 March 2026 killing 15 workers.Source: UNESCO / Iranian state media
Why are protesters from Isfahan being executed in Iran?
Demonstrators arrested during January 2026 anti-war protests in Isfahan face moharebeh charges (waging war against God) under the Islamic Penal Code, which carries a mandatory death penalty. Abbas Akbari Feyzabadi was executed on 25 May 2026 as the 15th person put to death for January-uprising activity.Source: IHRNGO / Amnesty International
