The Antechamber from Hogwarts Legacy is located inside The Athenaeum, hidden in the Restricted Section of the Library. While you're at it, you'll discover one chest outside The Athenaeum, two chests while exploring the quest's designated path, and two hidden chests.
We'll walk you through how to find the two hidden chests in the Antechamber quest. If you missed them while completing the quest, you may return them anytime to loot them.
In the Restricted Library Antechamber – Hogwarts Legacy, all hidden chest locations are revealed.
Aim at the rune on the top of the door and use a Basic Cast to attack it. Doing so will create a bridge, allowing you to cross to the other side. Once on the other side, defeat the guards to open the door leading further in (no battle if the quest already exists).
Enter the new room and defeat the enemies (no battle if the quest is already completed). Once the room is clear, look to your left to discover a chest hidden inside an arch. You must create a path to reach the chest.
Step on the left platform to create a bridge, which will slowly appear as you get closer to the chest. After looting the chest, return to the main clearing and proceed to the next room.
To spawn a bridge, aim for the rune on the top of the door, and use a Basic Cast like before. The bridge will vanish as you go closer to the other side, so just run and jump to cross safely.
Once inside the room, aim for the rune on the top of the door and launch it with a Basic Cast to spawn a platform on the right.
Jump onto the platform, aim at the rune on the top of the door, and dodge it with a Basic Cast once more. This will spawn a bridge connected to the platform, leading to the arch on the right. Follow the bridge's path and enter the arch to find the second hidden chest.
