Using non-invasive muon radiography, an international team of scientists and archaeologists has detected several previously unknown internal chambers within the Great Ziggurat of Ur in modern-day Iraq. This technology, which uses subatomic particles to peer through massive stone and brick structures, has revealed a series of vaulted corridors and a large central room that have remained sealed since the Neo-Sumerian period. These hidden spaces are believed to have served as structural reinforcements or ritual storage areas.
The discovery is being hailed as a major advancement in heritage preservation technology, as it allows researchers to explore the internal architecture of the 4,000-year-old monument without causing any physical damage. The data suggests the chambers contain large ceramic vessels and mud-brick altars. Plans are now being developed to use specialized robotic micro-cameras to enter these voids and provide the first visual confirmation of the contents, potentially offering new insights into the religious practices of the Third Dynasty of Ur.
