Hogwarts Legacy‘s Clock Tower has four secret rooms hidden behind the emblemed doors, each brimming with valuable loot for you to collect in the game. If you’re struggling with solving the puzzle, as it will require more than just the Alohomora spell, our comprehensive guide is here to help you kick the door down.
Throughout your Hogwarts adventure, you’ll come across various puzzles like the empty frame challenges and Arithmancy doors, with the Clock Tower puzzle offering some of the most enticing rewards.
As a brave student at Hogwarts, you’ll encounter numerous puzzles throughout the castle, such as the vacant frame puzzles and the symbolic Arithmancy doors, with the Clock Tower puzzle being among the most rewarding.
However, Hogwarts Castle also hosts a few specific challenges that aren’t quite so obvious and are aptly labeled as Hogwarts Secrets within the game.
One of those Hogwarts Secrets is hidden within the Clock Tower door and requires both intuition and a keen eye to figure out how to solve its puzzle. However, for players who are having trouble solving the Clock Tower door puzzle, this guide will break it down step by step.
Solving the Clock Tower’s mechanical door puzzle
First things first, students will need to have access to Arresto Momentum in order to complete this puzzle. Arresto Momentum is a spell that slows down an object or enemy’s movements and is earned by completing Madam Kogawa’s Assignment 2.
Next, head to the Clock Tower located in the South Wing of Hogwarts. Players should be familiar with the Clock Tower as it’s home to the Crossed Wands Dueling Club.

The Unicorn door is located on the ground floor of the Clock Tower.
Students will likely notice a door on the ground floor of the Clock Tower with a metal gate in front of it that opens and shuts every so often. This metal gate is actually timed with the pendulum swinging, and the Clock Tower contains three other doors just like it.
These doors can be opened by stopping the pendulum’s movement with Arresto Momentum at the right time. Students just need to know when to stop the pendulum and which door to access at the right time.
Opening the four doors in the Clock Tower
The four doors in the Clock Tower of Hogwarts Legacy can be opened in any order, but it’s easiest to work from top to bottom—as such, the door on the highest floor will be called the first door while the one on the ground floor will be called the fourth.
As players climb the Clock Tower through stairs located on either side of the entrance, they should notice a metal bar with symbols lining the pendulum’s path. The farthest right symbol matches the first door, while the farthest left symbol matches the fourth door.

The right symbol matches the first door, while the left matches the second door.

The left symbol matches the fourth door while the right matches the third.
From here, players simply need to cast Arresto Momentum while the Pendulum’s bar overlaps with the correct symbol for each door.
Each door will give the following reward:
- First door – Random Legendary gear piece
- Second door – Fwooper Statue conjuration
- Third door – Disillusionment chest (500 Galleons)
- Fourth door – Huge Decorated Table conjuration
Additionally, students should complete one of the Solve Hogwarts Secrets challenges and receive an item from the Challenges tab in the pause menu after opening all four chests.
