Nimrud is an ancient Assyrian city located south on the river Tigris in modern Iraq. In ancient times the city was called Kalhu. The Arabs called the city Nimrud after the Biblical Nimrod, a legendary hunting hero.
The city covered an area of around 16 square miles (41 km2). Ruins of the city are found in modern day Iraq, some 30 kilometres (19 mi) southeast of Mosul. The ruins are located in the District of Al Hamdaniya, within 1 kilometre (0.62 mi) of the village of Noomanea. Nimrud has been suggested as the site of the biblical city of Calah or Kalakh.
Excavations revealed remarkable bas-reliefs, ivories, and sculptures. A statue of Ashurnasirpal II was found in an excellent state of preservation, as were colossal winged man-headed lions weighing 10 short tons (9.1 t) to 30 short tons (27 t) each guarding the palace entrance. The large number of inscriptions dealing with king Ashurnasirpal II provide more details about him and his reign than are known for any other ruler of this epoch.
Portions of the site have been also been identified as temples to Ninurta and Enlil, a building assigned to Nabu, the god of writing and the arts, and as extensive fortifications.
Nimrud's various monuments are currently threatened by exposure to the harsh elements of the Iraqi climate. Lack of proper protective roofing means that the ancient reliefs at the site are susceptible to erosion from wind-blown sand and strong seasonal rains.
