Babylon · Iraq · 32.541781, 44.431644 · PYR record in the living atlas
Babylon carries more confusion between myth and record than almost any city in the ancient world, so it is worth sorting the piles before anything else. Solidly real: Hammurabi's law code, Nebuchadnezzar II's building programme, the Ishtar Gate with its glazed lions, bulls and dragons, dug out between 1899 and 1917 and rebuilt from original brick in Berlin. Unproven at Babylon: the Hanging Gardens, of which not one archaeological trace has ever been found on the site, and which the city's own detailed records never mention. Those two facts sit about a kilometre apart and get told as one story.
The gate in Berlin is the smaller one
Claudius James Rich made the first systematic survey of the ruins in the early nineteenth century. Robert Koldewey's German expedition began digging in March 1899 and uncovered the Ishtar Gate between 1902 and 1904, continuing until the First World War stopped the work in 1914; it remains the most comprehensive campaign the site has ever received. The team recovered tens of thousands of glazed brick fragments, enough to fill around 900 crates. The boxes travelled a long way round through the war years and reached Berlin by 1926, the year after Koldewey died. Walter Andrae began the reconstruction in 1928 and it was inaugurated in 1930.
Here is the part the postcards leave out. What stands in the Pergamon Museum is the front gate only, at slightly reduced scale. The second and larger gate behind it is in storage. The processional way leading to it, known as the Aibur-shabu, was a brick-paved corridor running north to south from the Ishtar Gate to the Esagila temple complex, over half a mile between walls some 15 metres high, carrying more than 120 striding lions. That axis was a planning decision rather than an accident of growth: it is the route of the Akitu New Year procession, and it is documented both in the excavation plans and in cuneiform texts. Ancient sources describe an eight-gated circuit within a system of inner and outer walls. The gate itself rose more than 11 metres. Nebuchadnezzar set a plaque in it saying, in his own words, that he had placed wild bulls and ferocious dragons in the gateways and adorned them with luxurious splendour so that people might gaze on them in wonder. He was not being modest, and he was not exaggerating either.
How the bricks were made
Babylon was a mudbrick city throughout, sun-dried brick and kiln-fired brick, with the glazed facing in deep blue, yellow and white reserved for the gate and the processional way. That matters for everything that has happened to the site since, because mudbrick is soluble and unforgiving, and it is the reason a wet century does more damage than a dry millennium.
The gate is a manufacturing achievement as much as an artistic one. Each animal was built from bricks individually moulded in relief, glazed, fired and then fitted together like a puzzle whose pieces work in only one arrangement. The workshops managed that with a system of fitters' marks, which Andrae worked out and recorded, including in a watercolour he made in 1901. The king's inscription was stamped into bricks before they were dried or fired. On one of them a dog walked across the wet clay and left a paw print, which is the most direct contact anyone gets with the brickyard.
The gardens
Now the wonder. Herodotus wrote about Babylon at length and never mentions a hanging garden. Every classical author who does describe it, Berossus as quoted by later writers, Cleitarchus, Philo, Strabo and Josephus, is later than the Neo-Babylonian city and mostly working at second or third hand. Koldewey proposed that a vaulted building in the Southern Palace was the substructure of the gardens, and he admitted in print that he was not convinced by his own identification. Nobody has done better at Babylon since.
The strongest alternative belongs to the Assyriologist Stephanie Dalley, set out fully in 2013. Her argument is that the wonder was real but stood at Nineveh, built by the Assyrian king Sennacherib in the seventh century BC. Sennacherib's own inscriptions describe a botanic garden planted beside his Palace Without Rival as a replica of Mount Amanus, watered by an engineered system that included cast metal water-raising screws, and Nineveh has the aqueduct works to support it. Greek writers, she points out, confused Assyria and Babylonia routinely, and Nineveh was itself sometimes called Babylon after the Assyrian conquest. The competing explanation, which several scholars prefer, is more deflationary: that Cleitarchus, writing up Alexander's campaign, inflated the ordinary palace gardens of Babylon into a marvel and everyone copied him.
One thing needs saying plainly before Dalley's case is repeated as a solved problem, because it usually is. No unambiguous archaeological trace of a garden structure matching the ancient descriptions has been found at either city. Nineveh included. Dalley's evidence is Sennacherib's inscriptions, an aqueduct system and palace reliefs: textual and circumstantial, considerably stronger than anything Babylon offers, and not an excavated garden. The wonder has a better address than it used to have. It still does not have a floor plan.
Our reading is that the negative evidence at Babylon carries unusual weight, and it is worth being exact about why, because the reason is not that the city has been thoroughly dug. It has not, as the next section says. The weight comes from the written record: Babylon is one of the best-documented cities of the ancient world in its own language, and a city that itemised its gates and its shrines did not forget to mention a terraced garden. That does not settle whether Dalley's Nineveh is right or whether the gardens are a literary invention. It does mean the burden sits with anyone placing them at Babylon.
Most of the city is still in the ground
Estimates from Iraqi authorities and from UNESCO put the proportion of the urban area never professionally excavated at somewhere between 80 and 95 per cent. Major structures, administrative archives and whole residential quarters may lie entirely unknown. Systematic remote sensing and geomagnetic survey have been proposed and have not been comprehensively applied.
Every sentence of the form "no evidence of X has been found at Babylon" has to be read against that number, this article's own sentences included. Absence of evidence from a site that is nine-tenths unopened is a weak instrument, and we would rather hand you the caveat than have you find it later.
Digging does continue. In 2024 a team led by Quhtan Abbas Hassan Aboud excavated at the Al-Fayadiya district site, Block 19/3, and recovered 478 artefacts: cuneiform tablets in Akkadian, cylinder seals and pottery vessels. Two residential structures were identified, with stratigraphic layers belonging to both the ancient Babylonian and the later Sasanian periods. That is what an ordinary season at Babylon still produces.
What Babylon wrote down about itself
The documentation is the point. A cuneiform text series known as Tintir, from its Sumerian name for the city, is a topographical catalogue of Babylon: its ceremonial names, its temples and shrines, its city gates, its streets and its districts, given in both Sumerian and Akkadian. Andrew George published the standard edition in 1992. Separately, a tablet copied at Uruk in 229 BC gives the dimensions of Etemenanki, the ziggurat of Marduk whose name means the house of the foundation of heaven and earth: seven stages, 91 metres high on a base 91 metres square. Koldewey excavated its foundation and measured 91.48 by 91.66 metres.
The base measurement is solid ground and the height is not. Nothing substantial of Etemenanki survives above ground, so the 91 metres is a reading of a text rather than a measurement of a building, and scholarly readings of that tablet differ; other readings of it produce a structure of roughly 90 metres, and the disagreement is about the text, not about the tower. What can be said is that the plan on the tablet and the foundation in the ground agree, which is rarer than it sounds. That tower is the most likely seed of the Tower of Babel story. Alexander had 10,000 men clear the ruin in the spring of 323 BC intending to rebuild it, then died in June. Today the site is a water-filled pit.
Even with that documentation, the published plans of the city are less solid than they look. Heather Baker has shown that the street layouts reproduced in book after book descend from Eckhard Unger's 1931 reconstruction and are largely conjectural, and that corrections made decades ago have gone on being ignored. When you see a confident map of Babylon, most of the lines on it are inference.
The alignment question, answered in the negative
This atlas is organised around alignment, so Babylon deserves an explicit answer rather than a silence. Babylonian astronomers were sophisticated observers, and celestial observation from the city is attested in its own texts. That is not the same as the built city encoding it. No peer-reviewed excavation report has shown Babylon's structures, its walls, its processional way or its temple enclosures, calibrated to any specific celestial event. Whether any of them were is an open question that nobody has answered with measurements.
The popular claim that Etemenanki's stages encode planetary cycles is a different case and gets a different answer. It rests on no published bearing data at all. There is no survey behind it to check. We are naming it so that it can be refused rather than left to circulate: absent a measurement, it is not a finding, and we will not repeat it.
What stands at the real site
At Babylon itself, in Iraq, the surviving lower gate and processional way still show animal reliefs in unglazed brick, alongside 1980s reconstructions raised directly on the ancient walls. UNESCO, which inscribed the site on the World Heritage list in 2019 under criteria three and six, records those reconstructions as based on conjecture rather than archaeological evidence and as having damaged the property's integrity. The listed property covers 1,054.3 hectares with a buffer zone of 154.5, and the general fabric is described as being in critical condition.
The damage most often reported is the military use of the site in 2003 and 2004, when coalition forces built a base on the archaeological ground, reported as Camp Alpha and also as Camp Babylon. John Curtis assessed it for the British Museum and UNESCO in 2005, and a fuller UNESCO report edited by Margarete van Ess and Curtis followed in 2009.
Concentrating on 2003 understates the rest, though. A good deal of the harm was self-inflicted and earlier. The Saddam-era reconstruction of the 1980s and 1990s laid modern yellow fired brick and poured concrete directly over and into the ancient mudbrick fabric. Mid-twentieth-century restorations trapped saline groundwater beneath concrete caps, which accelerated the decay of the original material underneath them. In a mudbrick city, a concrete lid is not a repair. Climate-driven erosion is now flagged as a further risk to major Iraqi sites, and work at Babylon has turned to age-old building techniques to deal with it.
It is not all one direction. Conservation work since the 2019 inscription has been addressing that damage, and by September 2025 the restoration was being reported as one of the things drawing visitors back to Iraq. The dragon of Marduk, a composite of snake, lion and eagle, walks the gate bricks in Berlin and in Babylon alike, and it has outlasted every one of these administrations.
What our engines found
We ran the same test here as everywhere else, with the settings fixed in advance and identical at every one of the fifty sites we cover: a 200 km search radius, at least 12 km between sampled sites, 15 sites, a 2 per cent tolerance, and 2,000 Monte Carlo runs against a null model resampled from real catalogued sites in the same region. The settings are frozen because the answer moves if you tune them, and tuning them after seeing the answer is exactly the trick we object to elsewhere. Babylon returned 32 golden-ratio pairs where chance predicts 34.7, giving p = 0.7221 (run on 1 October 2026).
That is fewer than chance would predict, and it is not significant. The control points the same way: the control ratio 2.0 scored 1.24 times its expected count against phi's 0.92, so nothing here singles out the golden ratio.
The collinear test is the one that does return something: 34 three-site alignments against 22.7 expected, p = 0.018. Before anyone builds on that, the honest caveat is terrain. Sites string out along river valleys, coastlines and narrow necks of buildable land, and geography produces straight lines without anyone planning them. It is a number worth investigating, not a conclusion.
We publish the misses because a tool that only reports its hits is not measuring anything. Every figure above is reproducible from the same coordinates, the same settings and the same seed. When the catalogue grows, the figures can move, so we rerun these tests and update this section rather than leave an old number standing.
One limit worth stating plainly, because it is the one most often glossed over. This test compares positions between monuments. It says nothing about any building's own proportions, its height, base, slope or perimeter. That is a separate question, and at several sites a genuinely open one.
