Reddit asked their users if they’ve ever seen a secret passageway and what happened when they explored said passageway. We’ve compiled our favorite answers here for your pleasure. Next time you decide to be brave and check out that dark hallway, you might think twice. More secret passageways.

My high school shop (industrial arts) class room had ridiculously high ceilings. Maybe 20 feet high. There was a closet area, maybe 6 foot across and 15 wide, that the teacher had converted to a “lacquer room,” adding an exhaust fan.

Anyway. In the process, he also added a (unsanctioned) second story. Drug up some carpet, a couch and chair from somewhere, plus a TV he’d tapped in to the school’s cable. I thought it was the coolest thing. Word had it that he lived up there when him and the Mrs. were having trouble.

The closest thing I’ve ever had to a “secret room” was the tornado shelter in my last house.

When my wife and I moved in, we went into the garage and discovered a trap door on the floor. The door led down to an underground tornado shelter. There were no lights. The stairs creaked horribly, the air was thick with dust, and the echoes sounded like something was walking towards you. To make things even worse, you had to go down the stairs backward, so you couldn’t see whatever evil monster was waiting for you in the dark.

I told my wife “That tornado shelter is scarier than a tornado. I’m never going down there.”

But later, we actually had a tornado warning. We grabbed flashlights and sleeping bags and rushed down there. It turned out, once you walked around the corner, the super creepy tornado shelter was bright pink and covered in lady bug stickers. Apparently the last owner’s little girl used it as a play room.

Had a small door (like think Being John Malkovich) in a room in a house I rented. The landlord told me “not to worry about it and never open it” of course that wasn’t going to do anything but make me want to open it. Sadly, it was a school lease, I took the place but had to sublet it to a friend for the summer cause I was going home. So I literally “took possession” and then handed the keys over to him.

So I finally move in months later and I ask him about the door, and he says, “oh me and the girlfriend call it the bathroom door, the guy was right you don’t want to open it.”

So WTF, of course I open it. Almost immediately after he’s gone.

Turns out they called it the “Bat Room” not the “Bathroom” door.

Door couldn’t be open for more than 10 seconds when fucking bats come flying out of the door. Only 3 or 4 but even one bat is like batshit crazy. Turns out he had opened it and had way more than that when he did, and had to get professionals to remove them and clean up the damage and didn’t want to tell me (or me tell the landlord). So at least he had the number of the guys who did the removal handy. They asked me “if we will ever learn.” Fucking Batroom door.

My high school had a vast network of tunnels starting under the stage. Found a sex couch, 2 bongs, 40 years worth of set pieces and the original plans for a highway that cuts through my town.

It’s not exactly a secret room, but rather a secret space. After my senior year of high school, I worked the summer as a laborer at the school- they were doing extensive renovations and they hired a few students to do the unskilled work so that they wouldn’t have to pay the contractor’s guys to do it. In the library there was the school vault which mostly held old records, blueprints, and some time capsule stuff. The vault was only about 7 feet high and the ceilings in that wing were about 10 feet. We tore out the old plywood and veneer that had filled the space between the vault in the ceiling and there was a motherlode of old stuff (presumably from the last time renovations had been done). There were notes from kids in the 1960s, some pictures, baseball cards, a pair of panties, and some old beer cans. So, we kept everything up there in its place, and then added some of our own: a picture of the four of us (with names on the back), a list of who the hot girls (and teachers) were at school, and I think a Skillet CD someone had in their car. We put it all in a box the next day, got back up on top of the vault and shoved everything just out of sight. The next week the contractor came in and bricked over crawlspace, so we assume that stuff won’t surface again until the building is demolished.

Unfortunately, we didn’t recognize any of the names on the stuff from the 60s, otherwise we’d have let them know. I sure hope somebody contacts us in 40 years.

My house had a secret room in the attic. It’s a really old house and the former owner was a pretty wealthy banker. The room was used as an opium den, and when the stock market crashed he hung himself in there.

A junior high school that I used to go to for language classes had a hallway at a corner of the building which was completely dark. The hall led to a stair well which was dark as well. The teachers always used to tell the students to never go upstairs, so naturally we formed “raiding parties” to find out what was upstairs. Idk why but you’d think it would have been easy to get a bunch of kids to run through a hallway and up some stairs, but there were a lot of failed attempts because the parties would fall apart because teachers came to stop us or kids would run back as soon as they got to the stairs cause they were scared shitless. Anyways it was after quite some time before we actually managed to reach the top of the stairs and what we saw up there reinforced the rumor that that place was haunted. Basically you walk up these steps in complete darkness and you are met with a bright painting of a clown or something at the top. Let’s just say there were no more attempts to explore further the upstairs anymore after that day.

My grandparents had a built-in bookshelf that could be pulled out of the wall to reveal a small space (about enough to fit 3 skinny people in). I never knew about it until a game of adult hide and seek and my uncle hid there, and my grandfather scolded him for revealing it.

There was a tile in our kitchen that you could lift up and there was a hole down to the laundry room in the basement. We usually just used it to talk to anyone that was down there, or a laundry chute if we were too lazy to go downstairs.

At my undergrad college, there was a series of what were called “steam tunnels.” Supposedly in the earlier history of the college, they were used to allow students to pass between buildings during times of gnarly winter weather, but they had been sealed off long before I got there. Unless… you knew how to get in. Most students thought they were a myth; the few of us - and judging by the number of people I saw down there, there probably were less than 100 out of 5,000 students who knew they really did exist - who did found a nice haven for - whatever. Makes sense that they were old, because they only went between the three oldest buildings on campus.

They were just really wide tunnels with high ceilings that did in fact carry steam pipes, so they were warm; there were some blind offshoots, but mostly they were just nice, wide thoroughfares that were fun to explore.

My parent’s old house in Kent, southern England, had a cellar that they filled in with rubble from the renovation work (and regretted doing ever after).

The house wasn’t wildly old - a bit of it was seventeenth century, some eighteenth, but there had certainly been a dwelling on that site for a long time.

Anyway, there was a tunnel heading out from the cellar, angled so it pointed directly at the church, which was on the other side of the road, and maybe a hundred yards away. The church is Norman: late 11th Century.

Almost certainly a smugglers’ tunnel. Village vicars and parsons were frequently part of the smuggling gangs in the 18th century, because it was not quite the right thing to search a church. And the 18th century saw a big upsurge in smuggling: “Four and twenty ponies, trotting through the dark. Brandy for the parson, baccy for the clerk.” as Kipling put it.

I imagine the tunnel’s still there.

I used to live in suburban Detroit where people had immense fear of breaking and entering. So, when we moved into our new house, the landlord showed us the ‘special cabinet.’ One of the cabinets in the office room off the living room was actually a passage-way tiny to a small room with some water bottles, gas masks, other important survival things. It had room for about 2 or 3 people.

Needless to say, we never used it.
