Nimrud Iraq: Inside The Ancient Assyrian Royal City Revealed

Nimrud, Iraq is the modern name for a city that once governed an empire from the Tigris plain. Ancient Kalhu, known in the Bible as Calah, lies southeast of Mosul and covers about 360 hectares. Founded during the 13th century BC and existing as a trade center by 1400 BC, it was remade in the early ninth century BC into the administrative capital of Assyria. Its story is one of deliberate urbanism, imperial art and archival loss that still shapes how we understand the Assyrian world.

Kalhu Rebuilt From Ruin Hills

Inscriptions of Ashurnasirpal II who reigned 883 to 859 BC record that Middle Assyrian ruler Shalmaneser I who reigned 1263 to 1234 BC had built the city Kalhu. By the time Ashurnasirpal ascended the throne, it had become dilapidated, lay dormant and had turned into ruin hills. That description was not literary exaggeration but urban fact. Ashurnasirpal chose the site precisely because it could be reimagined.

In 879 BCE, he made Kalhu his new administrative capital, adding a five-mile-long wall, a monumental stepped tower or ziggurat, new temples and a large palace covered in elaborate decoration. The city held this role as imperial capital from 883 to 706 BCE, with a longer history as an Assyrian city from around 1350 to 610 BCE. Its position southeast of modern Mosul placed it at the heart of the Nineveh plains, where the Tigris offered both transport and symbolic alignment. In 1850, Henry Rawlinson identified the mound as the Biblical Calah, confirming a continuity of name across millennia.

Kalhu served as Assyria’s administrative centre and main royal residence until Sargon II who reigned 721 to 705 BC founded Dur-Sharrukin, now Khorsabad, and moved the court in 707 BCE and then in 706 BC to his ideal city. Even after the court moved, Nimrud retained palatial functions and provincial administration, a layered history that makes its citadel a record of successive Neo-Assyrian kings and local governors renovating temple complexes first begun by Ashurnasirpal II.

The Northwest Palace And The Language Of Stone

The heart of Nimrud was the Northwest Palace of Ashurnasirpal II, built as a stage for kingship. Its walls were lined with large stone orthostats carved in low relief, standing 2.2 to 2.3 meters above ground level, designed to overwhelm the viewer with narrative. Winged figures with eagle heads, genies offering purification, the king in his fez-shaped peaked headgear hunting lions or receiving tribute, all rendered in gypsum with a precision that turns political message into tactile surface.

At gateways stood the colossal lamassu, winged bulls with human heads, protective deities that marked thresholds between exterior and interior power. Inside, storerooms held more than 100 bronze vessels stacked together, the Nimrud bowls found by early excavators, while other buildings labeled the South-East Palace or Burnt Palace yielded the famed Nimrud ivories, delicate carvings in elephant ivory that show Phoenician and Egyptian influence absorbed into Assyrian luxury.

The palace was not isolated. The citadel held a ziggurat, temples to Ninurta and Enlil and a wider architectural ensemble that positioned religion and administration within the same walled precinct. The Lower Town, now mapped by the University of Udine Nimrud Lower Town Archaeological Project using drones, magnetic sensors, satellite images and surface surveys, reveals a city beyond the royal center, with residential quarters and production areas that supported the court. Nimrud was the second capital of the Assyrian Empire, known as Kalhu or Kalah, flourishing during the reign of Ashurnasirpal, yet it was also a functioning provincial town for centuries after.

Rediscovery By Layard And The Archive Dispersed

Nimrud lay buried for over 2,000 years after the fall of the Assyrian Empire until British adventurer Sir Austen Henry Layard excavated Kalhu between 1845 and 1851 for the British Museum. Layard was ready on the morning of November 9, 1845 to begin digging. On the very first day of his excavations he uncovered the Northwest Palace and on the second day made the first discovery of ivories. Over the next six years he concentrated on the palace, recording reliefs and removing lamassu with the support of Stratford Canning, British ambassador to Constantinople.

The finds were sensational. Enormous bas-relief panels that lined the throne room walls, the throne back, eight panels from the southeast wall of the throne room, winged figures from the east wall and colossal gateway figures were shipped to London, Paris, Baghdad and Mosul. In 1849 and 1853 Layard published folio-sized illustrations in The Monuments of Nineveh, a work that introduced Assyrian art to a European public and established archaeological illustration as a discipline. Reliefs offered to missionaries by Henry Creswicke Rawlinson about 1853 were distributed to colleges including Dartmouth, where they remain in museum collections.

Most of Nimrud’s priceless artefacts had long been moved to museums in Mosul, Baghdad, Paris and London by the 21st century, yet giant lamassu and in situ reliefs remained on site, vulnerable precisely because they could not be moved without industrial effort. That vulnerability would become central to the site’s recent history.

"The reliefs stood 2.3 meters high for a reason. They were not decoration. They were governance rendered in stone."

Destruction And The Work That Follows

On March 5, 2015, Islamic State militants began demolition of Nimrud. A video released in April 2015 showed militants using heavy tools, electric drills, bulldozers and explosives to destroy lamassu and carvings. The local palace was bulldozed, the ziggurat was pushed into the ancient bed of the Tigris and reliefs were smashed with sledgehammers. By the time the city was retaken by government forces, 90 percent of the excavated zone, including Ashurnasirpal II’s palace, the ziggurat and its lamassu statues, had been completely destroyed. UNESCO condemned the destruction as a war crime, noting that deliberate damage of culture violates international norms.

The motive remains debated. The ziggurat ruins were the highest point in the surrounding Nineveh plains and could serve as a defensive position, yet the site is remote from strategic locations. The destruction was documented as high-definition propaganda, touting a campaign to purge what the group considered heretical. After standing for 3,000 years, the remains were systematically reduced to rubble, leaving ruins vulnerable to looters and further damage.

Since then, The Nimrud Rescue Project funded by the Smithsonian has worked on location to train local Iraqi archaeologists and protect and conserve remains. The Lower Town project continues to map the unexcavated city, revealing life beyond the royal center. Nimrud remains on the UNESCO tentative list, a status first submitted in the context of its Assyrian significance. Facsimiles of lamassu from the northwest palace have been donated to the University of Mosul as part of restoration of memory where restoration of material is no longer possible.

Essential Questions

Where is Nimrud located and what was its ancient name?

Nimrud is located southeast of Mosul in modern northern Iraq. Its ancient name was Kalhu, also spelled Kalhu, Kalchu and Kalach, known in the Bible as Calah or Calah. The site covers about 360 hectares on the Tigris plain.

When was Nimrud founded and when did it become an Assyrian capital?

A city existed at the site by 1400 BC and was built by Middle Assyrian ruler Shalmaneser I around 1263 to 1234 BC. It was re-established as the Assyrian administrative capital by Ashurnasirpal II who reigned 883 to 859 BC in 879 BCE, serving as imperial capital from 883 to 706 BCE until Sargon II moved the court to Dur-Sharrukin in 707 BCE.

What is significant about the Northwest Palace at Nimrud?

The Northwest Palace of Ashurnasirpal II featured a five-mile wall, ziggurat, temples and a palace whose walls were lined with large stone orthostats carved in relief standing 2.2 to 2.3 meters high, plus colossal lamassu winged bulls with human heads guarding gateways and more than 100 bronze vessels found by excavators.

Who excavated Nimrud and what did they find?

British adventurer Sir Austen Henry Layard excavated Kalhu at Nimrud between 1845 and 1851 for the British Museum, beginning on November 9, 1845. On the first day he uncovered the Northwest Palace and on the second day discovered ivories. His finds included lamassu, throne room bas-reliefs and Nimrud ivories, published in The Monuments of Nineveh in 1849 and 1853.

What happened to Nimrud in recent years?

On March 5, 2015, Islamic State militants bulldozed and destroyed Nimrud. By the time the city was retaken, 90 percent of the excavated zone including Ashurnasirpal II's palace, the ziggurat and lamassu statues had been destroyed. UNESCO condemned the destruction as a war crime, and projects like the Nimrud Rescue Project and University of Udine Lower Town survey now work to protect and document the remains.

Nimrud endures not because its stones remain intact but because its idea remains legible. A city planned from ruin hills, a palace lined with 2.3-metre narratives, a court that moved yet left its archive in stone. To study Kalhu now is to understand that Assyrian power was exercised through precision of image and permanence of wall. Even in absence, after bulldozers and fire, that precision still instructs.
