Archaeologists have uncovered the first and largest astronomical observatory from 6th century BC — located in Kafr Sheikh, Egypt.
The Egyptian Ministry of Tourism and Antiquities shared the remarkable discovery on Facebook on Aug. 23 along with photos of various artifacts found during the excavation.
"The Egyptian archaeological mission from the Supreme Council of Antiquities, working at the Buto Temple in Tell el-Faraeen area in Kafr El-Sheikh, has successfully uncovered the first and largest mud brick astronomical observatory, dating back to the 6th century BCE," the group wrote.

The observatory covers about half a mile.
It was used to observe and record astronomical findings, tracking the movement of the sun and stars in the temple in the city, according to the post.
"Its architectural design consists of a side entrance East where the sun rises, a hall of central columns open in the shape of the letter (L) and is fronted by a huge, high brick wall that leans inward, similar to the Egyptian style of calligraphy known in temple entrances," said the post.

The building is thought to measure sun inclination and shade and monitor sun movement hourly during the day.
It consists of about 15 feet-long limestone tiles, with five level blocks of limestone, three vertical and two horizontal blocks.
Archeologists found an inclined stone sundial, known as "the inclined shadow clock," which the Ministry of Tourism and Antiquities calls "one of the most prominent timekeeping instruments in ancient times."
The mission found five mud brick chambers likely used to store sophisticated tools, four additional small rooms, a large yellow-decorated hall with scenery and the remains of a blue painting.

"The Egyptians were among the most adept astronomers in ancient history, and their legacy echoes to this day," noted Science Alert in relation to the new findings.
"It was in Ancient Egypt that the 365-day calendar was born, and the 24-hour day. They completely mapped the night sky, and had their own constellations and zodiac, some signs of which are still recognized today."
The discovery of the observatory "is a significant contribution" to an understanding today of Ancient Egyptian astronomy and scientific practices, noted Ancient-Origins.net.
