Castlevania: Belmont’s Curse – How to Open the Gate to the Catacombs

A towering stone entrance marked by a green glow blocks the way to the Catacombs until you obtain three keys. Defeat three separate bosses to get them, then return to the entrance and fit each key into it. Installing the final gem opens the route into the Catacombs of Paris.

The three keys that open the gate

All three keys share the same item description: “One of three keys needed to open the sealed door to the Catacombs.” Each one names the boss you defeat to earn it, and each is a differently colored gem.

Key	Boss you defeat	Gem color
The Fallen’s Key	The Fallen	Purple
The Prophetess’s Key	Medusa	Green-blue
The Warrior’s Key	Joan of Arc	Orange

The Fallen’s Key

The Fallen is the first boss, fought in the Gate to the Catacombs district of Paris Streets. Beat him and you receive The Fallen’s Key, a purple gem whose item card reads: “One of three keys needed to open the sealed door to the Catacombs. Obtained by defeating The Fallen.”

After you press Continue, the banner “NEW OBJECTIVE / UNLOCK THE GATE TO THE CATACOMBS” appears over the tarot cards. The next card shown is The Prophetess, the boss whose key you need next.

Try the sealed gate with the key in hand and Rose says: “I need two other keys to open the gate. They should be held by two other guardians.” One key is not enough on its own. Move on to the next boss.

The Prophetess’s Key

Reach the Serpents’ Lair by way of the Ancient Sewers, which you can enter using the mirror at Holy Innocents’ Cemetery. Continue from there to face Medusa in the Ossuary of the Innocents. Her defeat awards The Prophetess’s Key, a green-blue gem. Inserting the gem illuminates a section of the seal, and The Fallen informs you that another key is needed.

The Warrior’s Key

Joan of Arc is fought on the Roof of the Tower in Paris Streets. Beating her rewards The Warrior’s Key, an orange gem. After this fight, the objective line on the map changes to “GET TO THE GATE OF THE CATACOMBS”, pointing you back toward the sealed door.

Where the Gate to the Catacombs is

In the Paris Streets map, the gate has its own district, Gate to the Catacombs, in the lower left beside the Abandoned Sewers. Its map marker says “GATE TO THE CATACOMBS”. During the key hunt, the objective line in the top right displays “UNLOCK THE GATE TO THE CATACOMBS”. If you lose your bearings, open the Abandoned Sewers sub-area map and follow the marker.

Opening the gate also needs Holy Light, the parry Joan of Arc gives Rose along with The Warrior’s Key, so you will have it by the time the third key is in. Walk right up to the door and you will see the prompt “GATE TO THE CATACOMBS / INTERACT [R1]” (PC: E).

How to place the keys and open the gate

After beating each boss, return to the sealed door and walk up until the “INTERACT [R1]” (PC: E) prompt appears. Press R1 to slot in the key you are holding.

Repeat this for all three keys. The purple Fallen’s Key, the green-blue Prophetess’s Key, and the orange Warrior’s Key each light up part of the seal as they go in.

Once the last key is installed, the door displays all three gems together. It opens, and pressing R1 (PC: E) lets you enter the Catacombs of Paris.

What happens when the last key goes in

Go back to the hall in Paris Streets where you fought The Fallen. The sealed door sits under a banner that reads “GATE TO THE CATACOMBS”.

Make sure you have The Fallen’s Key, The Warrior’s Key and The Prophetess’s Key in your inventory. Face the door and use Interact (E on PC). The view zooms closer as the purple, green, then orange gem sockets illuminate.

Let the conversation play out. You don’t need to make any choices. These are the lines:

Rose: “Time to find out if Medusa is telling the truth about reviving Dracula.”
The Fallen: “Rose, wait.” “If someone or something means to resurrect Dracula, it is likely more powerful than you, even with our help.” “Perhaps you ought to find your father.”
Rose: “No. I told Father I could handle this myself.”
Joan: “Be careful, young warrior. Victory will only be yours if your heart is pure and just.”
Medusa: “Hehehehe, yes! Nothing will stop you! The trap awaits…”
Rose: “It’s not a trap, Medusa. It’s a mystery to solve. And I will solve it.”

As the door shines open, it reveals a stone entrance marked “ARRETE!” A new “INTERACT E” prompt appears. Press Interact to descend into the Catacombs of Paris.

After the gate opens

The first room past the open door is the Catacomb Entrance, inside the Catacombs of Paris. The map objective then updates to “STOP THE RESURRECTION OF DRACULA”, which is your cue that the door is behind you and the next stretch has begun.
