📋 About This Mod
Did you make an epic settlement at the Castle? Did you use DDproductions mod to fix the walls? did you make the Castle look epic again?
Shame that no matter how much work you put in to the settlement up top the tunnels supporting your castle are falling apart and collapsing.
This Mod I made for myself but I decided to share it on here, it repairs the castle tunnels and turns it into a nice part of your castle.
The Containers I used in this mod's armory are from the Bunker 1 Alpha mod by Jpitner http://www.nexusmods.com/fallout4/mods/13668/? He gave me permission to use them in this mod.
I've also added some posters from this mod http://www.nexusmods.com/fallout4/mods/11975/?
This Mod does require the DLC's It adds an armor and weapons workbench to the tunnels as well as a robot workbench.
I have left SARGE in the tunnels as and have NOT touched the final room of the tunnels at all, so in theory the quest line shouldn't be broken by this mod and it should be safe to use any time however for immersion purposes at least I recommend completing the quest first and then switching it on.
This is just the first most basic version, I plan to do an updated version that fills all the shelves out and adds alot more clutter which I will post when it is finished, but some people might prefer the more cut down version so I'm going to upload that now :)
I may also do a version 3 with a grave/tribute to the general which would definitely break the quest and could only be used post-quest but would look alot tidier and a bit more immersive (that you would honor the fallen rather than leave him to rot) let me know in the comments if you'd like to see this.
The tunnel has been re-navmeshed as it was obviously inaccessible and uneven before, many of the rooms also had to be re-navmeshed because of the debris removal, It should work fine (piper followed me ok when I tested) but it may not be perfect. I also don't know if Ronnie follows a specific path during the questline or not.
Amendment!
WOW Guys, Thanks for so much love and support for this MOD. Many many people have asked me about doing a DLCless version of this mod, Once a mod has been assigned a master in the creation kit you can't remove it, I've tried to remove the items in the CK and then use FO4Edit to clean the masters and this has removed the Automatron and Wasteland workshop requirements but its still clinging on to the Far harbor Masterfile and I don't know how to remove it, I've added the version (1C) to files which now only requires far Harbor. if someone else wishes to take this file and remove the DLC association they are welcome to do so.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community favorite with over 3,000 endorsements—clearly a mod people love.
- Turns a broken, useless part of the Castle into something you can actually use.
- Huge download count (92k+) shows it's been tried and tested by many players.
⚠️ Cons
- Last updated in 2016—might have compatibility issues with newer game patches or DLC.
- Only affects the Castle tunnels, so it's a niche fix for settlement builders.
For Fallout 4 settlement builders who want to make the Castle a fully functional Minutemen HQ. If you're tired of those blocked-off tunnels and want to expand your stronghold, this is for you. Skip if you're not into settlement building or want gameplay changes beyond cosmetic fixes.
💡 Beginner Tips
- Make sure you have the Castle settlement unlocked before installing, or the mod won't have anything to restore.
- If you're using other Castle overhaul mods, check load order to avoid conflicts—place this one after major overhauls.
- Since it's an older mod, consider using a mod manager to easily enable/disable if you run into issues.
