The Royal Tombs of Ur are a group of ancient burial sites located in the city of Ur, in present-day Iraq. Dating back to around 2600-2400 BCE, these tombs were discovered in the 1920s by archaeologist Sir Leonard Woolley. They are notable for their elaborate construction and the wealth of artifacts found within, including jewelry, pottery, and ceremonial items. These tombs belonged to the rulers of the Sumerian city-state of Ur and reflect the social hierarchy of the time. The most famous tomb, known as the Great Death Pit, contained the remains of a queen and numerous attendants, suggesting practices related to royal burials and possibly human sacrifice.
