Egyptologists uncover 2,500 year-old observatory full of precise tools

Egyptologists have excavated a nearly 9,150-square-foot astronomical observatory in modern-day Tell el-Faraeen dating back to the sixth century BCE—the first and largest of its kind from that era. In an August 23 announcement from Egypt’s Ministry of Tourism and Antiquities (interpreted from Arabic to English using Google Translate), the mud brick structure contained numerous tools that, although comparatively simple in design, allowed for the precise study and measurement of solar calendrical dates related to Egyptian religious rites, royal coronations, and agricultural plans.
