An online colloquium was held in late 2022 to celebrate the centenary of Sir Leonard Woolley's first season of excavations at AlMuqayyar, the Babylonian city of Ur. This book publishes 18 papers from the colloquium by international scholars, together with a foreword from Dr Laith Majid Hussain, as President of the State Board for Antiquities and Heritage, and a recently unearthed report of J.G. Taylor's work at the site, written in 1858. The papers reevaluate Woolley's work, revisit his archives with fresh eyes and apply 21stcentury techniques to enrich our knowledge of the 7,000 year old city. They also include results from renewed work at Ur, undertaken by joint Iraqi and international teams of archaeologists. The papers highlight the value of welldocumented old excavations and the exciting potential of collaborations to explore new research questions, under the leadership of the Iraqi State Board for Antiquities and Heritage.
