After he died, it changed hands and the new owners discovered some hidden secrets. Built by Commodore Frederick G. Bourne in 1896, he put in secret passageways and a dungeon, so he could sneak around behind walls and eavesdrop on his guests. Now, it’s a tourist attraction.
Dexter’s House. Years ago, a redactor bought a house and posted a series of photos of a crawlspace he found in his attic. Up there was a strange door with a padlock. Once he opened it, he found a soundproofed room covered in plastic, with a platform in the middle, and a suitcase. Inside the suitcase was jewelry and several black tapes that had “No No No” written on them, and “Save yourself.”
Hidden Bedroom. According to an anonymous Redditor, two friends of theirs purchased an old farmhouse and found a secret door in a closet that was only a few feet tall. Inside was a bed that was too big to have fit in through the door. It looks like the room was built around the bed, and someone was locked in for a long time.
A Parisian Time Capsule. In 2010, a 91-year old woman passed away, and her executor discovered paperwork that she owned an apartment in Paris.

Inside were countless treasures, including a painting worth $3.4 Million.

Mout Sainte-Odile. In the Alsace region of France, is a 1,300 year old abbey. In 2000, they started to notice that books were going missing, and had no idea how. Every night, they’d lock the doors, they started sealing the windows and posted guards at the doors. Things were still going missing. They finally discovered that a young professor named Stanislas Gosse discovered a secret entrance and series of rooms, and was sneaking in nightly, to borrow old manuscripts.
Secret Toxic Mold. A young couple and their 2-year-old purchased a 5- bedroom home that was in foreclosure for a steal. When they started to do renovations, they found a passageway behind a bookshelf that led to a secret room. Inside, there was a note that said: “You Found It! Hello. If you’re reading this, then you found the secret room. I owned this house for a short while, and it was discovered to have a serious mold problem. One that actually made my children very sick to the point that we had to move out.” Apparently the previous owner had been trying to warn the realtor, the local authorities and anyone who’d listen, and he was shut down so the house could sell.
