BENEATH the labyrinthine salt caves and emerald mangrove forests of Qeshm Island in the Strait of Hormuz, a different kind of architecture lies buried.
While tourists once flocked to this “open-air geological museum” to get a glimpse of its surreal rock formations, the world’s gaze is now fixed on what lies beneath the coral: Iran’s “underground missile cities”, an Aljazeera Explainer said.
As the US-Israel war on Iran erupted, Qeshm has transitioned from a free-trade and tourist paradise to a front-line fortress – and the ultimate strategic prize for US Marines currently being deployed to the strait.
Its sheer size — approximately 1,445sq km (558sq miles) — allows it to physically dominate the entrance to the strait from the Gulf, acting as a cork in the world’s most vital energy transit passage.
These days, the island’s 148,000 residents – primarily Sunni Muslims who speak the unique Bandari dialect – live at the intersection of this ancient natural beauty and modern military tensions. Their lives are still dictated by the sea, which is celebrated every year during the Nowruz Sayyadi, Fisherman’s New Year, when all fishing stops to honour the ocean’s bounty.
But on March 7 – one week into the war – US air strikes targeted a critical desalination plant on the island. The strike, which Tehran branded a “flagrant crime” against civilians, cut off freshwater supplies to 30 surrounding villages.
In a swift retaliatory move, the Islamic Revolutionary Guard Corps (IRGC) launched strikes against US forces at the Juffair base in Bahrain, alleging the attack on Qeshm had been launched from a neighbouring Gulf state.
Today, the island’s modern industrial facade, bolstered by its status as a free trade-industrial zone since 1989, is overshadowed by its role as Iran’s “unsinkable aircraft carrier”.
Located just 22km (14 miles) south of the port city of Bandar Abbas, Qeshm dominates the Clarence Strait, also known as Kuran, and acts as the primary platform for Iran’s “asymmetric” naval power, say analysts.
While exact figures regarding the number of Iranian fast-attack boats and coastal batteries hidden within the island’s subterranean labyrinths remain heavily classified, their strategic intent is clear. Retired Lebanese Brigadier-General Hassan Jouni, a military and strategic expert, told Al Jazeera that Qeshm houses “striking Iranian capabilities” within what is described as an underground “missile city”. These vast networks, Jouni said, are designed for one primary purpose: to effectively control or close the Strait of Hormuz.
This, they have successfully done. Shipping traffic through the strait was effectively halted last week when Iran threatened to strike ships attempting to pass.
Now, only a handful of ships carrying vital oil and gas supplies to the rest of the world are being allowed through, as countries scramble to negotiate deals with Iran for their own tankers and as the administration of United States President Donald Trump attempts to assemble a naval convoy of warships to forcibly open the waterway.
As Qeshm becomes the focal point of a 21st-century energy war, however, its silent salt caves and ancient shrines serve as a reminder that while past empires and military coalitions like those of the Portuguese and British have eventually faded, the geological fortress of the strait remains anchored in the turbulent tides of history.
