I toured a home that had been vacant for years. The basement was a mess. Someone had been majorly into canning. Shelves had collapsed, shattering jars.
Other than that, it was a lot like touring a house while house hunting. Dirtier and more missing steps, but that’s it.
We used to walk through a mental hospital that was abandoned in the 80s. It was creepy as fuck all. Bed pans and beds in rooms still, utensils in the kitchen, narrow tunnels in the basement with shackles on the wall. It’s since been torn down.
I went to Plymouth, England while working on a ship and noticed an Island with an abandoned complex of buildings. We decided to row out with our small boat to check it out and it ended up being an abandoned artillery battery. It was a nice day out, kind of like spending the day walking around an overgrown garden with some WWII history thrown in. https://imgur.com/a/eoxGr
I grew up in a tropical island, and it was a (not well kept) secret that one of the resorts went bankrupt and was shut down. They kept the lights on and from a distance you couldn’t really tell there was no one there, and they had security guards patrolling the property… well, my partner and I, and young horny teenagers, decided it would be cool to sneak in and get naughty on the rooftop. That part was fun and all, but it was so cool to go through the empty hallways and rooms and play mission impossible when the security guards were nearby lol… I went back a few times to explore late at night, never got caught by any authorities thankfully 😅
