The City That Named an Era

There is a word — Babylonian — that has entered the languages of the world as a synonym for grandeur, decadence, and overwhelming scale. We speak of Babylonian excess, of Babylonian complexity, of things so vast and intricate that they defy ordinary comprehension. The word carries within it the memory of a city that was, for more than a thousand years, the greatest urban centre on Earth — a metropolis of temples and palaces, of scholars and merchants, of priests and kings, set in the flat alluvial plains of southern Mesopotamia between the Tigris and Euphrates rivers.

Babylon. The name itself is ancient — derived from the Akkadian Bab-ilim, meaning 'Gate of the Gods.' It was a city that believed itself to be the centre of the universe, the axis around which the cosmos turned, the place where heaven and earth met in the great ziggurat of Etemenanki — the tower that may have inspired the biblical account of the Tower of Babel. For the peoples of the ancient Near East, Babylon was not merely a city. It was an idea: the idea of civilisation itself, concentrated in stone and brick and water, sustained by the labour of tens of thousands and the ambition of kings who called themselves lords of the four corners of the world.

It was inscribed on the UNESCO World Heritage List in 2019 — a recognition long delayed by the catastrophic circumstances of modern Iraq, but no less significant for that delay. The site encompasses the ruins of one of the most consequential cities in human history, spread across more than a thousand hectares of the Mesopotamian plain, eighty-five kilometres south of Baghdad.

Mesopotamia — The Cradle

To understand Babylon, one must first understand the landscape that made it possible. Mesopotamia — the Greek name for the land between the rivers — is the flat, fertile plain created by the sediment deposits of the Tigris and Euphrates as they flow southward from the mountains of Anatolia and Kurdistan toward the Persian Gulf. It is not, by the standards of most great civilisations, a naturally imposing landscape. There are no mountains, no forests, no dramatic geological features. What it has, in extraordinary abundance, is water and soil — the two prerequisites of agricultural surplus, and agricultural surplus is the prerequisite of everything else: cities, specialisation, trade, writing, law, and empire.

It was in this flat, sun-baked plain that human beings first developed, between approximately 4000 and 3000 BCE, the complex of institutions and technologies that we call civilisation. The Sumerians — the earliest identifiable literate culture in the world — built the first cities here: Uruk, Ur, Lagash, Nippur. They invented writing — cuneiform script pressed into clay tablets with a reed stylus — to manage the administrative complexity of urban life. They developed law codes, mathematical systems, astronomical observations, and religious traditions of extraordinary sophistication.

Babylon was not among the first Sumerian cities. It appears in the historical record as a relatively minor settlement in the early third millennium BCE, overshadowed by the great Sumerian centres to the south. Its rise to prominence was neither inevitable nor rapid. It came, rather, through a combination of geographical advantage — its position at the junction of major trade routes — political opportunity, and the ambitions of a series of exceptionally capable rulers.

Hammurabi and the First Empire

The first great moment in Babylon's history came in the eighteenth century BCE, under the reign of Hammurabi (r. 1792–1750 BCE), the sixth king of the First Babylonian Dynasty. Hammurabi transformed what had been a modest city-state into the capital of an empire that encompassed most of Mesopotamia — from the Persian Gulf in the south to the upper Euphrates in the north.

Hammurabi is remembered today primarily for his law code — the Code of Hammurabi — a collection of 282 laws inscribed on a black diorite stele nearly two and a half metres tall, now housed in the Louvre in Paris. The code is remarkable not merely for its antiquity but for its sophistication. It addresses an extraordinary range of civil and criminal matters — property rights, commercial contracts, marriage and divorce, inheritance, wages, professional liability, and the treatment of slaves. Its famous lex talionis principle — 'an eye for an eye, a tooth for a tooth' — represents not barbarism but a significant advance in legal thinking: the principle that punishment should be proportionate to the offence.

Under Hammurabi, Babylon became the preeminent city of Mesopotamia — a position it would hold, with interruptions, for more than a thousand years. The city grew to encompass a population that ancient sources suggest may have reached several hundred thousand at its height — an extraordinary urban concentration for the ancient world.

Nebuchadnezzar II and the City of Wonders

Babylon's second and greatest moment of glory came under Nebuchadnezzar II (r. 605–562 BCE), the most celebrated ruler of the Neo-Babylonian Empire. It was Nebuchadnezzar who transformed Babylon into the city that has been celebrated and lamented ever since — the city of the Hanging Gardens, of the Ishtar Gate, of the great processional way, of the rebuilt Etemenanki ziggurat that may have inspired the Tower of Babel.

Under Nebuchadnezzar's direction, Babylon became the largest city in the world — a metropolis of extraordinary scale and ambition. The city was enclosed by a double ring of walls — the outer wall, known as Imgur-Enlil, extended for more than eighteen kilometres and was wide enough, according to the Greek historian Herodotus, for two four-horse chariots to pass each other on the top. The walls were reinforced at intervals by towers and protected by a broad moat fed by the Euphrates.

Within the walls, the city was laid out in a rough grid pattern — one of the earliest examples of urban planning in history — divided by the Euphrates, which ran through the centre of the city and was crossed by a great stone bridge. The principal axis of the city was the Processional Way — a broad, paved avenue lined with glazed brick walls decorated with lions in relief — that ran from the Ishtar Gate through the heart of the city to the great temple of Marduk, the Esagila.

The Ishtar Gate — the ceremonial entrance to the inner city, dedicated to the goddess Ishtar — was among the most spectacular works of ancient art ever created. Built of fired brick and faced with brilliant blue glazed tiles, it was decorated with alternating rows of dragons and bulls in raised relief — the sacred animals of the gods Marduk and Adad. The gate stood more than fourteen metres high and was approached by the Processional Way, its walls decorated with lions. The reconstructed gate — assembled from the original bricks excavated by Robert Koldewey between 1899 and 1917 — stands today in the Pergamon Museum in Berlin, one of the great monuments of ancient art.

The Hanging Gardens — Myth, Mystery, and Archaeology

No aspect of ancient Babylon has captured the imagination of subsequent civilisations more completely than the Hanging Gardens — listed by classical authors as one of the Seven Wonders of the Ancient World. The gardens were described by Greek and Roman writers as an extraordinary artificial mountain of terraced gardens, rising in stepped tiers above the flat Mesopotamian plain, irrigated by an elaborate system of water-raising machinery, planted with trees and flowers and shrubs from every part of the known world.

The problem is that no Babylonian text has ever been found that mentions the Hanging Gardens. Despite the enormous quantity of cuneiform records recovered from the site — administrative documents, royal inscriptions, astronomical observations, literary texts — not a single tablet refers to a garden of the kind described by classical sources. Archaeological excavation has found no clear physical remains that can be identified as the gardens.

This absence has led some scholars to question whether the Hanging Gardens were at Babylon at all the British Assyriologist Stephanie Dalley has argued, controversially, that they were in fact constructed at Nineveh by the Assyrian king Sennacherib. Others maintain that the gardens existed but have not survived in a recognisable form, given the erosion of the mudbrick structures over two and a half millennia. The question remains open — one of the most tantalising unsolved puzzles of ancient history.

Babylon in History — Conquest, Decline, and Memory

Babylon's political history after Nebuchadnezzar is a story of conquest, partial recovery, and eventual decline. In 539 BCE, Cyrus the Great of Persia entered the city — apparently without significant resistance — and incorporated it into the Achaemenid Empire. Cyrus famously presented himself not as a conqueror but as a liberator, restoring the temples, repatriating the gods that Nabonidus, the last Babylonian king, had brought to the city, and permitting the Jewish exiles — brought to Babylon by Nebuchadnezzar — to return to their homeland. The Cyrus Cylinder, a clay barrel inscription recording these acts, is often cited as an early declaration of religious tolerance and human rights.

Alexander the Great entered Babylon in 331 BCE after his decisive defeat of the Persian king Darius III at the Battle of Gaugamela. Alexander intended to make Babylon the capital of his empire — he began restoration work on the Esagila and Etemenanki, which had been damaged by the Persian king Xerxes — but he died in the city in 323 BCE before his ambitions could be realised. His death in the palace of Nebuchadnezzar, at the age of thirty-two, was the end of the brief Macedonian chapter in Babylon's history.

Under the Seleucid successors of Alexander, the city gradually declined as the new capital of Seleucia-on-the-Tigris drew away its population and trade. By the first century BCE, Babylon was largely abandoned. The mudbrick structures of which it had been built — magnificent when maintained but extraordinarily fragile when neglected — began their long dissolution back into the Mesopotamian plain.

Archaeological History and the Challenges of Conservation

The systematic archaeological investigation of Babylon began in earnest with the work of the German archaeologist Robert Koldewey, who excavated the site between 1899 and 1917 on behalf of the Deutsche Orient-Gesellschaft. Koldewey's meticulous excavations revealed the plan of the inner city, identified the Ishtar Gate and Processional Way, and recovered the glazed bricks from which the gate was subsequently reconstructed in Berlin. His work established the discipline of Near Eastern archaeology on a rigorous scientific footing.

The site suffered serious damage during the regime of Saddam Hussein, who initiated a reconstruction programme in the 1980s that involved building modern walls and structures directly on top of ancient remains — a project driven by political symbolism rather than archaeological principle. Saddam identified himself with Nebuchadnezzar and had bricks stamped with his own name placed alongside ancient bricks in the reconstructed walls — an act of historical appropriation that has been widely condemned by archaeologists.

Further damage was sustained during and after the 2003 invasion of Iraq, when a military camp was established on the site by coalition forces — an act that caused measurable damage to ancient surfaces and has been the subject of ongoing scholarly criticism. The subsequent instability of Iraq made sustained conservation work impossible for many years.

Reflection — The Weight of the Name

To stand at Babylon today is to stand in a place that has been weighted, for three thousand years, with the accumulated significance of human memory. The ruins are, by the standards of many ancient sites, unspectacular — low mounds of eroded mudbrick, partially reconstructed walls, the Lion of Babylon standing in a scrubby enclosure. The landscape is flat and featureless, the sky enormous.

But the name is everywhere. It is in the Hebrew scriptures, where Babylon is the great oppressor, the city of captivity, the whore of Babylon drunk on the blood of the saints. It is in Greek literature, where it is the greatest city in the world. It is in the Revelation of John, where Babylon becomes the symbol of all earthly power arrayed against the divine. It is in the reggae music of Jamaica, where Babylon is the system of oppression that the righteous must resist. It is in the languages of a hundred cultures, where Babylonian remains a synonym for the vast, the intricate, and the overwhelming.

No other city — not Rome, not Jerusalem, not Athens — carries quite the same weight of accumulated symbolic meaning. Babylon is not merely a place. It is an idea, a myth, a warning, a memory. To inscribe it on the World Heritage List is to acknowledge, however belatedly, that the physical ruins of this city — eroded, damaged, and imperfectly preserved as they are — carry within them something irreplaceable: the material record of the place where the story of human civilisation first achieved its most ambitious early expression.

Babylon — Iraq's Ancient City of Wonder and Myth

✦ Conclusion

Babylon is one of the most mythologised cities in human history — a name that has come to mean both greatness and decadence in equal measure, a city whose reputation has always been larger than its ruins could fully sustain. And yet the archaeological reality of Babylon is remarkable enough on its own terms. The greatest city of the ancient Near East for much of the 2nd and 1st millennia BCE, it was home to the famous Hanging Gardens, the Tower of Babel (almost certainly a ziggurat called Etemenanki), the Ishtar Gate, and the law code of Hammurabi.

The Ishtar Gate alone — now partially reconstructed in the Pergamon Museum in Berlin — gives you a sense of the colour and ambition of ancient Babylon. Covered in deep blue glazed brick and decorated with alternating rows of dragons and bulls sacred to the city's gods, it was one of eight gates in a city wall so massive that chariots could turn around on top of it. To walk through such a gate was to enter a space explicitly designed to communicate divine power and royal authority.

Babylon's inscription as a UNESCO World Heritage Site in 2019 was long overdue, delayed by decades of war, occupation, and the damage caused by a US military base constructed within the archaeological site during the 2003 Iraq War. The work of restoring and protecting this extraordinary site — so fundamental to the story of Western civilisation itself — is a responsibility that extends far beyond Iraq's borders.

✦ Frequently Asked Questions

Q1: Where is ancient Babylon located?

Ancient Babylon is located approximately 85 kilometres south of Baghdad in modern Iraq, near the city of Al-Hillah in Babil Province. The site sits on the east bank of the Euphrates River, in the heart of what the Greeks called Mesopotamia — 'the land between the rivers.'

Q2: Did the Hanging Gardens of Babylon really exist?

This remains one of archaeology's great unresolved questions. The Hanging Gardens are described in detail by ancient Greek and Roman writers, but no definitively identified remains have been found at Babylon. Some scholars argue they may have been located at Nineveh, or that they were a literary invention.

Q3: What was the Tower of Babel?

The Tower of Babel described in the Book of Genesis is widely believed by scholars to be based on Etemenanki, a massive stepped temple tower (ziggurat) in ancient Babylon dedicated to the god Marduk. It reached approximately 90 metres in height and was one of the most impressive structures in the ancient world.

Q4: What damage did Babylon suffer during recent conflicts?

During the 2003 Iraq War, a US military base called Camp Alpha was constructed within the Babylon archaeological site. Military activities caused significant damage including compaction of archaeological layers, damage to ancient brickwork, and the removal of soil containing artefacts for use in sandbag construction.
