Overview: What Are Clockwork Castellans In Resident Evil 4 Remake?
Clockwork Castellans are the hidden all collectibles endgame reward collectibles added to Resident Evil 4 Remake, replacing the original Blue Medals from the 2005 release. Each chapter has exactly one, for a total of 16 across the entire campaign. You destroy them with any weapon (even a knife punch works if you’re close enough) to check them off your list.
These are the most lucrative hidden items in RE4R, because full completion unlocks the best endgame weapon for New Game+ and speedruns. There’s no second chance to grab a missed one — once you leave a chapter, it’s gone. That’s why this location guide is mandatory if you want that infinite ammo Chicago Sweeper without starting a whole new playthrough.
| Clockwork Castellan Tier Ranking (By Difficulty To Find) | Chapters | Missable Risk |
|---|---|---|
| S (Easy, obvious) | 1, 2, 5, 9, 12, 15 | Low (1/10) |
| A (Hidden but predictable) | 3, 4, 7, 8, 10, 16 | Medium (4/10) |
| B (Easy to walk past) | 6, 11, 13 | High (7/10) |
| C (Almost guaranteed miss) | 14 | Extreme (9/10) |
Region-by-Region: All Clockwork Castellan Locations (Numbered Checklist)
Follow this numbered checklist in order as you play through the campaign. I’ve included exact map references and step-by-step directions to find all 16 without wasting time hunting.
Chapter 1: Village - 1/16
Immediately after you exit the cabin where you fight the first chainsaw sisters, head left up the dirt path towards the gate that leads to the village square. Before you go through the gate, turn around and look up at the ruined stone watchtower on your right. The Castellan is perched on the railing halfway up. One pistol shot will knock it down.
Map reference: Quadrant B4, upper edge of the village entrance.
Chapter 2: Village - 2/16
After you get the Hexagonal Emblem from the church and open the gate to the lakeside, follow the road past the fisherman’s hut. Stop at the broken wooden bridge leading down to the dock. Look left down the cliff edge — the Castellan is sitting on a small rock outcrop sticking out over the water.
Map reference: Quadrant C2, just west of the Lakeside Settlement.
Chapter 3: Lakeside - 3/16
After you defeat Del Lago and crash the boat on the far shore, follow the path up to the ruins entrance. Just before you go through the stone arch into the courtyard, look to your left against the cliff wall. There’s a small dilapidated shed — the Castellan is on top of the shed’s roof, tucked behind a tree.
Map reference: Quadrant A2, northwest of the Fish Farm.
Chapter 4: Lake Back Side - 4/16
When you get control of the boat after picking up the Insignia Key, head to the small northern dock at the abandoned factory (the same dock you start at after killing Del Lago). Face the cliff behind the dock — the Castellan is halfway up the cliff, tucked into a small stone niche. You can shoot it from the dock with a sniper rifle or get closer for a pistol shot.
Map reference: Quadrant A1, northern cliff face above the Abandoned Factory dock.
Chapter 5: Castle Gate - 5/16
After you lower the drawbridge and enter the castle courtyard, head to the left side of the courtyard. There’s a large cannon you use to blow open the castle main gate. The Castellan is sitting right on top of the cannon barrel. You can’t miss it if you remember to check before you fire.
Map reference: Quadrant B3, Castle Courtyard left side.
Chapter 6: Castle Water Hall - 6/16
After you drain the water in the Water Hall and fight the two Garradors, head through the door to the southern staircase. Before you go up the stairs, turn around and look at the bottom of the central pillar that used to be under water. The Castellan is tucked into the base of the pillar, right between two chains.
Map reference: Quadrant C4, Water Hall lower level, central pillar base.
This is one of the most commonly missed, because most players run straight up the stairs after draining the water. Slow down for 10 seconds to grab it.
Chapter 7: Castle Dining Hall - 7/16
After you kill the armored El Gigante in the courtyard, go through the door to the dining hall. The Castellan is sitting on the chandelier hanging in the center of the room. Shoot it with a pistol before you lower the chandelier to get the treasure.
Map reference: Quadrant B2, Castle Dining Hall center ceiling.
Chapter 8: Castle Treasury - 8/16
When you enter the Treasury after defeating Ramon Salazar’s right hand, head to the far left corner of the room (from the entrance door). The Castellan is tucked on the ledge behind the large statue of the lion. You’ll have to aim around the statue’s paw to hit it.
Map reference: Quadrant C3, Treasury northwest corner.
Chapter 9: Castle Clock Tower - 9/16
When you climb the clock tower and get to the top platform where the large clock face is, stop before you pull the lever to open the gate. Turn around and face the open air — the Castellan is sitting on the outer railing right behind the lever. Just walk up and shoot it.
Map reference: Quadrant C1, Clock Tower top platform.
Chapter 10: Island Cargo Depot - 10/16
After you exit the elevator into the Cargo Depot, head right along the catwalk towards the shipping containers. Stop at the first container stacked on top of another one. The Castellan is sitting on the corner of the top container, facing the catwalk. Easy shot with a pistol.
Map reference: Quadrant C3, Cargo Depot upper catwalk, first stacked container.
Chapter 11: Island Battery - 11/16
After you fight the Sturm mini-boss on the moving walkway, you exit into a room with a Merchant and a typewriter. Before you go through the door to the next area, turn around and look at the large ventilation fan above the exit you just came through. The Castellan is stuck in the fan’s grille. Shoot it through the gaps.
Map reference: Quadrant A3, post-Sturm safe room entrance, above the door.
Most players walk straight past this, because the fan is above the door you don’t need to go back through. Turn around once you spawn in, that’s all you need to do.
Chapter 12: Island Waste Disposal - 12/16
After you kill the two Iron Maidens in the Waste Disposal and open the large door leading up, check the right wall of the room before you leave. There’s a small control panel inset into the wall — the Castellan is sitting right on top of the panel. One shot, done.
Map reference: Quadrant B4, Waste Disposal lower level, right side exit wall.
Chapter 13: Island Experimental Facility - 13/16
After you get the Level 2 Keycard and ride the elevator down to the lower level, exit into the cryogenic freezing room. Walk all the way to the far end of the room, to the wall opposite the elevator. The Castellan is sitting on top of the broken cryogenic tank in the corner.
Map reference: Quadrant C3, Cryo Room far end corner.
Chapter 14: Island Incubation Lab - 14/16
This is the single most missable Clockwork Castellan in Resident Evil 4 Remake. After you defeat Saddler’s first form in the incubation lab and escape the self-destruct sequence, you run down a long linear corridor towards the hangar. Halfway down the corridor, there’s a small break room on your left. The Castellan is on the microwave inside the break room.
90% of players run straight past this room because the self-destruct timer is screaming and you’re being chased by a super regenerator. Stop for 2 seconds — the regenerator won’t enter the room with you, so you can shoot the Castellan and leave with zero risk.
Map reference: Quadrant B2, Self-Destruct Corridor, left side break room, microwave top.
Chapter 15: Island Hangar - 15/16
After you fight Krauser in the knife fight and exit into the hangar where the jet is parked, head towards the tail of the jet. The Castellan is sitting on the top of the tail fin. Shoot it from the ground with a rifle or pistol, no climbing required.
Map reference: Quadrant C4, Hangar jet tail fin.
Chapter 16: Volcano Saddler Arena - 16/16
After you cross the first stone bridge into the volcano area, before you climb the ladder up to the Saddler arena, turn right and look at the rock wall along the lava. The Castellan is sitting on a small rock ledge sticking out over the lava. Shoot it from the bridge, don’t worry about falling in — the hitbox is generous.
Map reference: Quadrant B1, Volcano approach, right side lava ledge.

Missable Items Warning: Can You Go Back For Missed Clockwork Castellans?
Absolutely not. Capcom designed Clockwork Castellans to be one per chapter, and they despawn permanently once you load the next chapter. There is no post-game free roam in Resident Evil 4 Remake that lets you go back to previous chapters to grab missed collectibles.
If you missed one, your only option is to start a New Game (not New Game+) and collect all 16 again in a single playthrough. That’s why this checklist is non-negotiable — just check off each one as you go, and you won’t have to waste 8 hours replaying the whole campaign.
The only exception is if you’re playing on PC with mods — you can use a save editor to manually add missing Castellans to your save, but that’s cheating for most players and doesn’t count towards the in-game challenge unlock.
