The Men of Letters Bunker is a secret underground headquarters located beneath an abandoned-looking power station in Lebanon, Kansas. From the outside, it looks like a forgotten industrial building surrounded by fencing, concrete, metal, and old equipment—nothing that suggests there is an enormous base hidden underneath. To get inside, you go through heavy, secure doors and down into a maze of underground hallways. The bunker feels old but well-kept, with concrete walls, dark wood details, steel doors, exposed pipes, humming lights, and old-fashioned switches and control panels. It has the look of a 1950s research facility mixed with a military bunker. The center of the bunker is its huge library, which works as the main meeting place and research room. It is filled with tall bookshelves packed with ancient lore books, files, maps, and records. Heavy wooden tables sit in the middle beneath green desk lamps, and the Men of Letters symbol is built into the floor. There are also bedrooms for Sam and Dean, a kitchen and dining area, a garage where the Impala can be kept safely, a medical room, storage areas for weapons and hunting supplies, and locked holding rooms for dangerous creatures or prisoners. Some parts of the bunker are darker and less welcoming, with narrow utility tunnels, sealed doors, hidden rooms, and areas that feel untouched for years.
