10 Ancient Monasteries Permanently Shut Down After What Monks Were Hiding Inside

10 ancient monasteries. All of them still operating. All of them holding rooms their own monks sealed on purpose. In 1975, a construction project at Saint Catherine's Monastery in Sinai broke through a wall and found a chamber no living monk had any record of, twelve unknown codices and over a thousand parchment folios spanning the 4th through 12th centuries. Scholars are still finding previously unknown texts in the collection today. Without that accidental discovery, the room would still be sealed and no one would know it was there. At Montecassino, the monastery that produced the founding document of Western monasticism, the monks evacuated ahead of a Lombard invasion in 577 AD, sealed Benedict's tomb beneath the oratory floor, and didn't return for more than a century. At the origin of it all, in Egypt, Anthony, the founder of Christian monasticism itself, gave his disciples one final instruction in 356 AD: seal the cave, tell no one where it is. The cave sits 1,200 stone steps up a desert cliff, still controlled by the same monastery seventeen centuries later, never independently examined, photography forbidden. Murals inside were whitewashed and stayed hidden for 700 years with no surviving explanation why. The pattern across all ten is the same. Not invaders. Not accident. Not time. The people who lived inside made the decision to seal what they knew. Subscribe and tell us where you're watching from. #history #monastery #mystery #ancienthistory #religion
