Jerusalem Room Reveals 30 Medieval Graffiti, Knights Sketch Lions at Last Supper

Last Supper room in Jerusalem just coughed up 30 graffiti and 9 medieval doodles—knights, lions, Latin, and a Christian woman from Aleppo etched into Mount Zion’s ancient stones. Researchers, armed with 3D scans and ground-penetrating radar, answered “Who left graffiti at the Last Supper?” and “What symbols are hidden in Jerusalem’s holy sites?” Archaeologist Amit Re’em quipped: “We managed to reach every corner of the Last Supper room. We even managed to penetrate inside the ancient stones.”
After 3D lasers swept those ancient stones, a Styrian nobleman and a Swiss knight emerged from the shadows, immortalized by scrawled names and a lion’s head in the Cenacle. How old are Jerusalem’s Last Supper graffiti, and which medieval pilgrims left secret notes? The team’s multispectral imaging cracked a centuries-old travel log, revealing that sword-toting royalty once doodled at Jesus’ table—imagine a pilgrimage selfie, but with chisel and candle instead of hashtags.
Among the 30 graffiti, a 1421 diary entry by Johannes Poloner sits beside a lion sketch, casting Mount Zion as both medieval chat room and art studio.
