Ammon News - A mysterious hand imprint was discovered carved into a 1,000-year-old dry moat that surrounded Jerusalem’s Old City during excavations of defensive fortifications, the Israel Antiquities Authority said in a statement Wednesday.

The archaeological work, carried out as part of an infrastructure project along Sultan Suleiman Street, which runs adjacent to the city walls, revealed a deep rock-hewn moat likely dating from the 10th century, or possibly even earlier, the IAA said.

At one point along the moat’s wall was a handprint carved into the stone, leaving archaeologists baffled as to its purpose.
