Venturing into the mechanical depths of The Citadel in Hollow Knight: Silksong, you will inevitably hear whispers of a powerful artifact known as the Cogwork Heart. This guide provides a comprehensive walkthrough for ambitious explorers, detailing how to locate every Cogheart piece, solve the challenging puzzles that guard them, and ultimately use the completed heart to awaken a mysterious mechanical sentinel.

What is the Cogwork Heart?


The Cogwork Heart is a unique Key Item that, once assembled from three scattered pieces, serves a singular grand purpose: to re-energize a dormant guardian. Unlike standard upgrades, its function is not immediately obvious, with only cryptic clues from characters like the Underworks Architect hinting at its true potential. Unlocking its secret grants you a powerful, albeit unconventional, ally in your journey through the kingdom.

Prerequisite: Acquire the Double Jump Ability


Before you begin your hunt, a crucial warning: you cannot complete this quest without the Double Jump skill. The final Cogheart piece and the chamber to use the heart are both locked behind platforming challenges that require this essential mobility upgrade. Ensure you have obtained it before setting out.

Cogheart Piece Location #1: The Choral Chambers


Your journey begins in the northwestern section of the Choral Chambers. This area is defined by its haunting, melodic ambiance and architectural elegance.
  • The Puzzle: As you enter the chamber housing the fragment, you will encounter a musical puzzle. A sequence of bells will ring out, and you must carefully listen and memorize the order.
  • The Solution: Using your needle, strike the corresponding bells in the exact sequence you heard. Precision is key; a mistake will reset the puzzle, forcing you to listen again.
  • The Reward: Upon a successful performance, the mechanism securing the first Cogheart piece will disengage, allowing you to claim it.

Cogheart Piece Location #2: The Whispering Vaults



The second fragment is hidden deep within the Whispering Vaults, accessed through a specific route from the Cogwork Core area.


  • Finding the Entrance: From the main machinery rooms of the Cogwork Core, you must navigatetowards the less-traveled, quieter tunnels that lead to the Vaults. This area is often shrouded in a low mist and features archival machinery.
  • The Puzzle: Another musical challenge awaits, but this one is more complex. Thesequence of bells is longer and the tones are subtler, requiring sharpauditory focus.
  • The Solution: Exercise patience. Let the sequence play through twice if needed. Onceconfident, replicate the melody perfectly with your needle to secure the second piece.

Cogheart Piece Location #3: The Memorium


The final and most well-guarded piece resides in the Memorium, a solemn and isolated location.


  • Access: This area is exclusively reachable with the Double Jump ability. Youwill need to navigate a series of high, precarious platforms to gainentry.
  • The Puzzle: The final musical test is the most intricate, potentially involvingmultiple layers of notes. The game may try to mislead you with echoeffects or overlapping sounds.
  • The Solution: Stand in the center of the room to hear the sequence clearly. Take your time—there is no penalty for waiting. Success here grants you the lastCogheart piece and automatically combines them into the complete Cogwork Heart.

How To Use the Cogwork Heart in Silksong


With the heart now restored, its true purpose can be fulfilled. Your destination is the Cogwork Core.


  • Locate the Sleeping Sentinel: From the main bench in the Cogwork Core, head left into a largemachinery room. Instead of going up, carefully glide down the centralshaft, avoiding spinning gears and enemies. On a ledge to the left, youwill find an opening.
  • The Final Ascent: Head left, watching for a break in the ceiling. Use your double jump to reach the upper chamber. Clear away the fragile junk blocking your path to the right.
  • Awaken the Guardian: In the next room, you will find a massive, imposing robot encased inglass. Shatter the glass and approach it. A prompt will appear to insert the Cogwork Heart.
  • The Choice: You can choose to walk away, but inserting the heart triggers amagnificent cutscene. The sentinel awakens, whirring to life withnewfound energy, before bursting through the chamber and flying off into The Citadel.
  • What Happens After?


    This is not the end of your interaction with this mechanical giant. Onceawakened, you will begin to encounter the sentinel across The Citadel.You will find it engaged in combat with powerful enemies, effectivelyclearing out difficult areas or providing a strategic distraction.Awakening it is a pivotal moment that dynamically changes theenvironment and offers invaluable assistance in your battle against theencroaching infection.


    By following these steps, you will unlock one of Silksong's most rewarding and fascinating side quests, turning a dormant machine into aformidable ally.
