“The stone was meant to contain it. The prayers were meant to silence it. Neither was enough…”
Deep in the mountains, hidden away from the world, stands a monastery concealing a dark secret buried deep beneath its foundations.
For centuries, its devoted monks guarded a soul stone believed to contain a powerful demon. But the stone's power began to fail. Guided by the demon's whispers, local miners dug into the monastery's underground chambers, slowly losing their minds as the corruption spread. They tore through the sacred halls, destroying everything in their path, desperate to open a portal to Hell.
They partially succeeded.
The ground beneath the monastery cracked open, allowing Hell itself to spill into the mortal realm.
The monks and miners met their end — or something far worse. The surviving locals sealed the monastery's doors and fled, leaving the cursed ruins to rot in the mountains.
Now, something evil is waiting inside.
---------------------------------------------
**PLEASE READ THE DESCRIPTION!**
---------------------------------------------
A desecrated monastery built for Forgotten Hollow, designed to replace Straud's mansion. Perfect for evil vampires, demonic entities, or an unholy religious cult. And if you own the Paranormal Stuff pack, you can turn it into a haunted residence filled with restless spirits.
I made this lot for my own gameplay, where I'm playing an evil, possessed vampire Sim, but I hope you'll have just as much fun with it!
๐๏ธ Lot Information
- World: Forgotten Hollow
- Lot size: 40 × 30
- Recommended placement: In place of Straud's mansion
- Build type: Monastery / haunted castle / demonic hideout
- Underground levels: 3
**IMPORTANT — LOT SIZE:** I've tested the build on a fresh save, and it places correctly on the 40 × 30 Straud's mansion lot. However, I've encountered issues when placing it on other lots, even other 40 × 30 lots, where some of the stairs on the ground floor disappear upon loading. I have no idea why — The Sims 4 is buggy enough as it is, and stairs have always been particularly glitchy. Honestly, I'm tired of fighting this game's bugs, so I recommend placing the build specifically on Straud's mansion lot.
If you do decide to place it on a different lot, check my troubleshooting notes below for instructions on how to put the missing stairs back.
๐ฆ Required Packs
The base version requires only these three packs:
- ๐งช Get to Work
- ๐ก Get Together
- ๐ฆ Vampires
I've also included optional versions with additional objects for those of you who own more packs.
Optional Versions
- ๐ป Paranormal Stuff — Includes a séance table, and the lot is set as a Haunted House Residential lot.
- ๐ Cottage Living — Includes an animal shed disguised as a cave (for a black llama), a different fridge, crocheting supplies, the Wild Birds tree, and a dedicated area for oversized crops.
๐ฏ๏ธ What's Inside?
I've included plenty of hidden features — by that, I mean I've disguised modern objects as medieval or supernatural furnishings by hiding them behind, or combining them with, other objects. Your Sims can use many of these objects automatically, but finding the exact spot to click if you want to trigger an interaction manually can be tricky.
Please take a look through the screenshots to see where everything is and how some of the hidden objects work!



There's quite a bit packed into this build, so here's a quick rundown of what's actually in it:
- ๐ฅ Everything for your Sims' basic needs: a stove, fridge, wooden toilet throne, toilet bush, bath, and more.
- ๐จ Various activities: a game table, painting easel, pipe organs, and bookshelves.
- ๐ฅ Fire everywhere: numerous fireplaces and several bonfires to keep the monastery suitably infernal.
- ๐ A little piece of Hell: a lava pool, lava hot tub, lounge chair hidden beneath the stone, and a stone diving board — made for demons and other hellish spirits.
- ๐ A dark portal: the Get to Work portal has been changed into a sinister stone gateway surrounded by bonfires, with a chemistry lab hidden behind a dark altar. You can use the portal to summon strange creatures (if you customize your aliens).
- โฐ๏ธ Vampire essentials: coffins and a treasury for storing your ill-gotten riches.
- ๐ฏ๏ธ Forbidden rituals: a séance table on the lowest level, right beside another dark altar.
- ๐๏ธ Three underground levels: explore dark dungeon halls and infernal depths.
Everything is fully functional and has been thoroughly playtested.
*If you want to summon creatures through the portal without having the game constantly generate new random aliens, I recommend No New Random Townie Generated Mod by Cepzid (amazing mod).
โ๏ธ A Few Important Notes
- NO Custom Content: No CC has been used in the build itself! It's made using the base game and the packs listed above, with lots of DEBUG objects. You may spot custom-content outfits on the Sims shown in the screenshots, but again, no CC has been used for the build itself.
- Light all the fireplaces if you want the build to look exactly as it does in the screenshots.
- Cooking together: If you want your Sims to cook together, simply remove the red stone from one of the kitchen counters.
- MoveObjects cheat: I don't believe you need `bb.moveobjects` enabled anymore when placing lots from the Gallery. However, if anything looks misplaced, try entering `bb.moveobjects on` in the cheat console before placing the lot. Just in case.
- If there's something you don't like or feel is a bit too much, just feel free to remove it.
- If the build feels too heavy for your PC, or you simply want to improve performance while playing, try removing the blood stains on the walls and floors and cleaning up the dungeon halls. That should cut the builds load on your pc by half.
๐งช Chemistry Table
- I'm working on a mod to remove the scientist career restriction from the chemistry table. In the meantime, you can already unlock new recipes by getting breakthroughs through interactions with the portal.
- Only the Synthesize Serum interaction works. I wasn't too bothered by the blocked Experiment interaction, since I don't want my Sims randomly conducting experiments anyway — the animation still looks a little too modern and wonky for this setting. But if you'd prefer to have both interactions available, just move or remove the Vampire book sitting on the table. That's what's blocking the interaction.
๐ Portal Text
If you want to get rid of the modern wording used for the Get to Work portal, download my GTW Portal Text Override mod. It changes the portal's text to fit a dark fantasy setting.
๐ฆ Recommended Mods
This build goes well with my Paranormal Stuff Override mod. It mainly retextures the paranormal objects that appear around the lot, replacing their Ghostbusters-movie vibe with something darker and more natural-looking, so they blend in better with the surroundings — a better fit for a haunted monastery or an old castle.
Performance tip: If the build is too big for your PC or you want to improve loading times, my Forgotten Hollow: Lights Out mod can help. It removes a lot of unnecessary clutter and lighting from the world, helping it load a little faster and run more smoothly.
๐งฑ Installation Instructions
1. Download the ZIP file.
2. Extract its contents.
3. Drop all the extracted files into your game's Tray folder.
The Tray folder is usually located here:
`Documents\Electronic Arts\The Sims 4\Tray`
4. Then open the Gallery in-game and find the lot in your Library.
๐ ๏ธ Troubleshooting
A. Missing stairs on other lot sizes
As mentioned above, some stairs may disappear when you load the build on a lot other than the intended 40 × 30 lot. Unfortunately, I haven't found a way to prevent this from happening.
If you encounter this issue, you can try placing the stairs manually:
1. Go to the floor directly above the missing stairs.
2. Select the stairs tool and use the Ctrl key while placing the stairs down to the floor below.
3. If the game refuses to place them correctly, try enabling `bb.moveobjects on` first.
B. Infinite loading screen
If you ever get stuck on an infinite loading screen when trying to enter the lot, try going into Build Mode first and letting the game load everything in the background and build up its cache. Wait a minute or two, then return to Manage Worlds and try entering the lot again.
I've mostly experienced this after a game update or after clearing the cache, when the game had to load everything from scratch again. It shouldn't normally happen every time you visit the lot.

Enjoy! ๐ค
I built this for my own game, but I really hope more people have fun exploring it this Halloween. Happy Halloween! ๐
