Ennigaldi-Nanna's museum is thought by some historians to be the first museum, although this is speculative. It dates to circa 530 BCE.[1][2][3][4] The curator was Ennigaldi, the daughter of Nabonidus, the last king of the Neo-Babylonian Empire.[5] It was located in the state of Ur, located in the modern-day Dhi Qar Governorate of Iraq, roughly 150 metres (490 ft) southeast of the famous Ziggurat of Ur.[6]
