Sacred memorial grounds within the Citadel preserving Pharloom's ancient history and forgotten cultural memories.
The Memorium is an area in The Citadel in Hollow Knight: Silksong. [Missing information]
Memorium is compact but packed with callbacks; clear it methodically to secure the last Flea, final Cogheart Piece, and new tools.
Accept the Lost Merchant setup, climb in from Songclave, grab the map, solve the bell puzzle, collect key pickups, then rescue the Huge Flea and find Jubilana toward Putrified Ducts.
Donate 500 Rosaries to complete Strengthening Songclave if needed.
Then accept The Lost Merchant (Jubilana missing) so progress counts while in Memorium.
From Songclave, head upper‑left past Grand Reeds; jump to high ledges.
Cut the thick vines blocking the ceiling path and hop up into Memorium.
Rest at the ground‑level right Bench, then take the next right exit and head down.
In the model‑Citadel room, buy the map (70) after passing Skull foes and a Rhinogrund.
From the map room, climb to the upper‑right bell puzzle chamber.
Stand on the plate and repeat bell sequences to raise the pedestal and claim the Cogheart Piece.
Traverse spike segments to a small chamber and loot the Pilgrim for a Memory Locket.
Use safe pogo/float to minimize damage on return.
Open gates and levers en route to the station alcove.
Pay to unlock the station for quick access in/out.
In the big central chamber, platform to the marked alcove.
Collect the Spool Fragment and keep the loop moving left/right.
Break glass to the right and pass the electric corridor (clawline timing).
Loot Materium, then break the upper right wall; defeat two Memoria to claim Volt Vessels (two bench‑configurable modes).
Hit the lever to open the vertical route, break left struts to link back to the top of the main shaft.
At the summit, free the Huge Flea; survive its charge pattern until it retreats—counts as rescued.
Return to the map room; climb to the cloth and exit to the exterior balcony.
Drop to the lower path, defeat Drapeflies/Drapelords, and speak to Jubilana to finish The Lost Merchant.
