Ennigaldi-Nanna's museum, Archaeological ruins in Al-Nasiriyah District, Iraq.

Ennigaldi-Nanna's museum is a ruined mud-brick complex at Ur, about 150 metres southeast of the Ziggurat of Ur, within the ancient building called E-Gig-Par that held Ennigaldi's living quarters and subsidiary rooms. Inside a temple beside the palace, dozens of artifacts were found in 1925 arranged side by side, their ages differing by centuries, each accompanied by a clay-drum label.

Princess Ennigaldi, daughter of King Nabonidus of Babylon, established this collection in the 6th century BCE as one of the earliest museums. This project marked a turning point when people began intentionally gathering and preserving knowledge for study.

The clay drums that served as labels were inscribed in three languages or registers: Sumerian, Akkadian/Babylonian, and a more accessible form of contemporary Babylonian. This suggests the labels were meant for different readers, likely priests, scribes and students. The museum pieces were used to explain the history of the area and the material heritage of Ennigaldi's dynasty.

The excavated area lies about 150 metres southeast of the Ziggurat of Ur, in the Dhi Qar Governorate. Ground is uneven where Woolley's trenches exposed the palace and temple complex, so wear sturdy shoes and carry water; shade is scarce. The site can be reached from the nearby ziggurat on foot.

Many clay tablets found here bear labels and descriptions written in multiple ancient languages, showing how objects were catalogued in antiquity. These early documentation methods made the building a model for museum practice thousands of years before modern institutions existed.
