Assyrian capital of Kalhu (Calah), founded in 883 BC by Ashurnasirpal II (883-859 BC) over the ruins of an earlier city built by Shalmaneser I (1274-1245 BC) in 13th century BC. It is located by Tigris River, south of modern Mosul (Iraq) in Mesopotamia. It was the third capital city, with Assur and Nineveh, of Assyria. The statues and inscriptions found by Sir Austen Henry Layard was one of the first archaeological discoveries to stir the public imagination. Its wall was some 8 km in circuit, enclosing at one corner a citadel which contained a ziggurat, temples, and palaces. The palaces have yielded the richest finds, enormous stone winged bulls, reliefs, and exquisite carved ivories which once adorned the royal furniture. Another rich collection of ivories was found in the arsenal of Shalmaneser III in the outer town. Some of the ivories show traces of the fire which accompanied the overthrow of the city by the Medes in 612 BC. Unlike many of the cities of Mesopotamia, Nimrud was not a long-lived site occupied from the prehistoric period. Its heyday continued until c 710 BC when the capital was transferred first to Khorsabad and subsequently to Nineveh. Many of the sculptures were brought back to England by Layard and are now in the British Museum.
