• Golestan Palace in Tehran was damaged amid the conflict between Iran and the US.
• The UNESCO World Heritage Site was affected by debris and shockwaves from a nearby strike.
• UNESCO expressed concern over the damage and urged the protection of World Heritage sites.

For over 400 years, the Golestan Palace and its ornate mirror halls, lush gardens, and intricately tiled facade have stood as a testament to Persian opulence and the artistic and political heritage of Iran.

The palace, originally built as part of a royal citadel in the 1500s and later renovated and expanded into a royal residence in the 18th and 19th centuries, has remained through centuries of dynastic upheavals, the 1979 Islamic Revolution, and the country's recent history.

Now, the historic site faces a painful chapter after the US-Israeli strikes on Iran left the palace damaged.

On February 28, the US and Israel launched a joint military operation targeting Iranian leadership in Tehran, escalating tensions into a wider regional conflict.

Within days, the Golestan Palace was damaged by the debris and shock wave that followed an airstrike in the nearby Arag Square, UNESCO said.

The UN agency released a statement expressing concern over damage to the palace and said it had shared the coordinates of nationally significant and World Heritage sites with "all parties concerned" in an effort to help prevent further destruction.

Under international law — including the 1954 Hague Convention — cultural landmarks like Golestan Palace are protected during armed conflict.

As the war continues, the loss in human life and culture is yet to be determined. The damage to Golestan Palace offers one of the first visible signs of how the fighting is affecting Iran's historic sites.

See how it was affected.

The Golestan Palace was originally built over 400 years ago as part of the royal citadel under the Safavid dynasty.
