Hatra (Persian: هترا, Arabic: الحضر al-Ḥaḍr) was an ancient city in the Ninawa Governorate and al-Jazira region of Iraq. It was known as Hatra in Persian and al-Hadr in Arabic, a name which appears once in ancient inscriptions, and it was in the ancient Persian province of Khvarvaran. The city lies 290 km (180 mi) northwest of Baghdad and 110 km (68 mi) southwest of Mosul.
On 7 March 2015, various sources including Iraqi officials reported that the militant group Islamic State of Iraq and the Levant (ISIL) had begun demolishing the ruins of Hatra. A video released by ISIL during the next month showed the destruction of the monuments. Hatra was liberated in March 2017.
