On a hot, quiet stretch of the Persian Gulf coast, between a cliff of tombs and a sea that laps at broken walls, lie the ruins of a city that once ran the world's richest ocean. For two and a half centuries Siraf was the great gateway of the Gulf — its ships sailing to China and back, its merchants absurdly wealthy, its captains the men whose real voyages became the tales of Sindbad the Sailor. Then the trade moved, the earth shook, and the sea came in. Today the quays lie underwater and the great port is a scatter of stone by a fishing village. This is what the end of an empire of trade looks like.
Siraf (بندر سیراف) lies on the northern shore of the Persian Gulf, at the modern village of Taheri in Bushehr province, roughly halfway down Iran's long southern coast. There is not much to the place now: a small fishing town of a few thousand people, a cliff behind it pocked with ancient tombs, a shoreline of foundations that the sea is slowly reclaiming. Nothing about it announces that this was once one of the greatest ports on earth — a city whose population historians estimate ran into the hundreds of thousands at its height — which is exactly what makes standing here so strange.
Because between about 800 and 1050 CE, Siraf was the beating heart of Indian Ocean trade. This was the Gulf's principal deep-water port, the place where the monsoon-driven sea routes to India, South-East Asia, Tang and Song China and the coast of East Africa all came home. Its warehouses held silk and porcelain, pearls and ivory, spices and gemstones; its merchants were bywords for wealth; excavations have turned up Chinese coins and ceramics, ivory from Africa, and lapis lazuli carried all the way from Afghanistan. A dry, waterless spot with no farmland to speak of grew rich on one thing only — the sea, and the nerve to cross it.
It was old even then. The excavations showed that Siraf was already a working port under the Sasanians, centuries before Islam — most likely the maritime outlet for the great inland city of Gor (Firuzabad), its deep foundations traced below (the timeline picks up the dates). When the Islamic golden age turned the Indian Ocean into a single connected marketplace, Siraf was perfectly placed to become its western gate — and for two hundred and fifty years, it did.
Siraf sits on the Gulf coast at Taheri, between Bushehr and Bandar Lengeh, with Kangan the nearest sizeable town. The inland city it once served, Firuzabad, lies across the Zagros to the north; the excavated ruins run along the shore and up the cliff of tombs behind, with part of the ancient harbour now submerged offshore.
Siraf's whole arc is the story of a road: it rose when the ocean road ran through it, and fell when the road moved on. Seven moments trace the whole life of the port.
Siraf is already a harbour serving the inland Sasanian city of Gor (Firuzabad), with a fortress on the site tentatively linked to Shapur II — the deep foundation the later boom was built on.
As the Abbasid golden age knits the Indian Ocean into one marketplace, Siraf becomes the Persian Gulf's principal port — the western terminus of the sea route to China.
Peak wealth. Sirafi merchants and captains sail to Canton and back; the city fills with Chinese porcelain, African ivory, Afghan lapis and spices, and builds one of Iran's earliest great mosques.
The merchant Sulayman and later the Sirafi captain accounts record the sea road to China in detail — the real, documented voyages that stand behind the legend of Sindbad.
Earthquakes strike the coast and damage the city; popular tradition fixes on a great quake around 970, though the decline is better understood as gradual, with tremors accelerating a fall that trade was already causing.
Gulf trade shifts toward the Red Sea and rival ports like Kish rise; Siraf's commercial dominance drains away, and with it the reason for a great city on a waterless shore.
David Whitehouse's excavations for the British Institute of Persian Studies recover the mosque, bazaars, houses and workshops — and prove the port's deep Sasanian roots, bringing the lost emporium back into history.
Everyone knows Sindbad the Sailor — the merchant of the Thousand and One Nights who sails into one impossible adventure after another and comes home rich. Fewer know that the fantasy floats on fact, and that the fact has an address. The seafaring world that produced Sindbad was the world of Siraf: the Gulf captains who really did point their ships east on the monsoon, cross the whole Indian Ocean to India and China, and return — if they returned — as wealthy and weathered as any story could ask.
The evidence is not just romantic. A Sirafi captaincy left written accounts of the China route as early as the ninth century, and it is those documented voyages, retold and embroidered in the ports and bazaars, that scholars regard as feeding the Sindbad tales. The Corning Museum of Glass, which holds Whitehouse's Siraf excavation archive, notes plainly that the captains of Siraf were among the sources behind the legend. Sindbad is fiction; the terror and the fortune of his ocean were not.
So the ruin by the fishing village is not just an old port. It is the harbour the storyteller was thinking of — the actual quay from which the actual ships set out to earn the tales. Stand on the shore and the direction is still there: east, into the monsoon, toward everything worth the risk.
Siraf is an open ruin-field, not a restored monument — atmospheric, lightly signed, and best read before you arrive. Four things anchor a visit:
The raised platform and foundations of Siraf's congregational mosque, one of the earliest in Iran, built at the height of the boom on the site of an earlier Sasanian structure — the civic heart of the rich port.
Traces of the commercial city: market rows, and the footprints of large multi-storey houses whose plastered, decorated rooms once belonged to merchants grown rich on the China trade.
Cut into the rock behind Siraf, rows of rock-hewn graves and cisterns — the city's dead set above the sea their living crossed, and one of the most evocative parts of the site.
Along and beyond the shoreline, walls, quays and structures now lie partly submerged — the literal edge of the sunken port, where the ruin passes from land into the Gulf that reclaimed it.
Siraf is a low-difficulty, high-resonance site: easy enough to walk, but remote, hot, and lightly interpreted, so its rewards go to those who bring the history with them. Its Adventure score reflects the long coastal journey and the raw, unmanaged ruin; its Legacy is very high — a world-historic port, the home of Sindbad's captains, and the haunting fact of a city the sea took back.
You come down a long, hot coast road to a small fishing village, and at first you think you have the wrong place. There is a sleepy harbour, a cliff, some low broken walls in the sun. Then someone tells you what you are looking at, and the quiet becomes deafening. This was Siraf — the port that traded with China when Europe was a backwater, the richest gateway of the richest ocean on earth, a name spoken with awe from Baghdad to Canton. And it is gone so completely that you nearly drove past it.
You walk out over the foundations, and the scale starts to whisper. Here was the great mosque; here the bazaars; here the tall houses of merchants so wealthy their names were proverbs. Up on the cliff behind, the tombs of the people who built it all. And then you reach the shoreline and understand the cruelest part: the ruins keep going, out past the waterline, walls and quays sunk beneath the shallows — because the sea that made this city rich is also the sea that swallowed it. You are standing at the exact seam where a world capital passes underwater.
That is the vertigo of Siraf. Not a single wonder to gasp at, but a whole vanished world you have to rebuild in your head — the ships, the fortunes, the captains setting out east on the monsoon toward everything dangerous and worth having. It is the setting of Sindbad with the fantasy stripped off, leaving only the truth underneath: that people really did sail from this shore into the unknown for gold, and that the ocean, in the end, took back both the gold and the shore. The greatest port of its age, and you can stand in the waves where its streets used to be.
The greatest port of the medieval ocean, home of the captains who became Sindbad — grown rich on the sea, and in the end swallowed by it.
November to March is when the Gulf coast is warm, mild and a pleasure — the time to walk an open ruin by the sea. Clear light on the water and comfortable air make this the season Siraf is meant for.
Late March and October or early November are workable shoulders — hotter and more humid than midwinter but still manageable if you start early and carry water.
June to September the Bushehr coast is brutally hot and humid; a midday visit to a shadeless ruin is genuinely dangerous, not just uncomfortable. If you must, go at dawn and leave before the heat builds.
Early morning or late afternoon always — low sun over the water is both kinder to walk in and far better for seeing (and photographing) the ruins and the drowned shoreline.
The wonder is a world-historic ruin by the sea, best reached in winter and best understood if you read first. Practicalities, etiquette and the questions people ask are below.
Siraf takes some reaching — it is a long way down the coast from anywhere — but the roads are good and the site is free and always open.
Siraf lies on the Persian Gulf coast at the village of Taheri (Bandar-e Taheri) in Bushehr Province, southern Iran, between Bushehr city and Bandar Lengeh — roughly 220–240 km south-east of Bushehr along the coastal road. It is an open archaeological site by the sea, reached by car; Kangan is the nearest town of any size, and Bushehr or Shiraz make the wider base.
Between about 800 and 1050 CE, Siraf was one of the greatest ports on earth — the Persian Gulf's main gateway for long-distance sea trade, connecting the Middle East with Tang and Song China, India, South-East Asia and East Africa. Its merchants dealt in silk, porcelain, pearls, ivory, spices and gemstones and were famously wealthy; excavated finds include Chinese coins and ceramics, East African ivory and Afghan lapis lazuli. It also holds one of the earliest congregational mosques in Iran.
By reputation, yes. Siraf's captains and merchants sailed to China and back across the Indian Ocean, and their real voyages and traveller's tales are widely regarded as a source that inspired the stories of Sindbad the Sailor in the Thousand and One Nights. The Corning Museum, which holds Whitehouse's excavation notebooks, notes that Sirafi captains were among the sources behind the Sindbad tales. Sindbad is a literary figure, but the seafaring world he came from was Siraf's.
A combination of forces, not a single disaster. From the eleventh century, Gulf trade shifted toward the Red Sea and Siraf's commercial dominance faded, while earthquakes repeatedly damaged the city and drowned part of the harbour beneath the sea. Popular accounts sometimes blame one great earthquake around 970 CE, but archaeologists describe a more gradual decline driven mainly by the loss of trade, with quakes accelerating it. By the later medieval period the great port was largely abandoned.
By the British archaeologist David Whitehouse for the British Institute of Persian Studies, in cooperation with Iran's Archaeological Service, over seven seasons from 1966 to 1973. The excavations established that Siraf was already a port in the Sasanian period — probably the port of Gor/Firuzabad, with a fortress tentatively linked to Shapur II — and uncovered the great mosque, bazaars, houses and workshops. Whitehouse's final report was published in 2009.
An open coastal ruin field rather than a restored monument: the foundations and podium of the congregational mosque, traces of bazaars and merchant houses, cliffside rock-cut tombs above the town, and the shoreline where quays and structures lie partly submerged offshore. It is atmospheric and historically extraordinary but lightly interpreted, so read first or go with a guide; the setting between cliff and sea is half the reward.
Winter — roughly November to March — when the Gulf coast is warm, mild and pleasant. Summer here is extremely hot and humid and a midday visit to an open, shadeless site is genuinely punishing. The cool season is also when the coast is at its most inviting for combining Siraf with the wider Bushehr shore.
Siraf makes most sense as one end of a line — the sea end of a road that ran up over the Zagros to the Sasanian heartland. Inland lies Firuzabad, the circular city of Gor that Siraf served as a port: capital and harbour, the two ends of one ancient artery of trade. And along the coast the story continues out to sea, into the islands and shores that inherited the Gulf commerce Siraf once ruled — the painted island of Hormuz, the underground water-city of Kish, and the tidal mangrove forests of Hara where the Gulf meets the land.

Trace the trade road whole: stand in the ruined port at Siraf where the ships came home, then drive inland to the round city of Gor they were feeding, and out along the coast to the islands that took the commerce when Siraf's tide went out. It is one of the great object lessons of Iran's south — that wealth built on a road lasts exactly as long as the road runs through you, and that the sea gives and takes with the same hand.
Untamed Iran prefers official, scholarly and first-hand sources, and separates what is established from what is popular tradition. Siraf is unusually well documented — a major modern excavation, a UNESCO Tentative dossier and a published final report underpin the essentials. The following are the sources this page draws on:
Facts last reviewed July 2026. Established: Siraf's location at Taheri, Bushehr; its Sasanian origin and ~800–1050 CE peak as a principal Persian Gulf trading port linking China, India, South-East Asia and East Africa; the Whitehouse excavations of 1966–1973 and their finds (great mosque, bazaars, houses, workshops, cliff tombs); the Chinese, African and Afghan trade goods; UNESCO Tentative List status (Iran submitted Siraf's nomination dossier in early 2026 and selected it as its official candidate for World Heritage inscription that year, though it is not yet inscribed). Well-attested tradition: the link between Siraf's real captains and the Sindbad tales, supported by the ninth-century Sirafi accounts of the China route and stated by the Corning Museum. Debated / simplified in popular sources: the decline is often blamed on a single great earthquake around 970 CE, but scholarship describes a gradual fall driven mainly by the shift of trade to the Red Sea, with earthquakes accelerating it; the fortress attribution to Shapur II is tentative. Approximate: road distances, the ~6,000 km figure for the sea road, and the map marker.
