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.
The facility is located within a sprawling archeological site now known as the Temple of Buto (the Greek name of the Egyptian god, Wadjet), and is located about 50 miles east of Alexandria. Built in the southeastern portion of the temple, the astronomical complex featured an east-facing entrance for sunrises, an L-shaped open central hall supported by columns, and a high, inward sloping mud brick wall “resembling the style of the Egyptian edifice known in temple entrances,” according to the government’s statement.
