Hogwarts Legacy Cache in the Castle Third Landmark: Location Guide

8 September 2026 | 3

Exploring the sprawling corridors and hidden alcoves of Hogwarts Castle offers endless discovery for young witches and wizards. Among the many early side quests, Cache in the Castle stands out as a charming treasure hunt assigned by Arthur Gaethly. This quest requires players to decipher a sketched treasure map depicting three distinct landmarks hidden throughout the school grounds. Finding the third landmark is often the trickiest part for players navigating the complex layout of the castle.

Understanding the Treasure Map Details

The quest begins when you speak with Arthur Gaethly in the Astronomy Wing, where he provides a illustrated map. The document depicts a rhinoceros skeleton, a central courtyard fountain, and a mysterious painting hidden in a stairwell. While the first two clues are relatively straightforward, reaching the final location requires following the map's visual directions closely.

Understanding how these clues chain together helps ensure you do not wander aimlessly through the massive corridors. Each landmark acts as a navigational waypoint guiding you toward the final secret. Paying attention to environmental details makes tracing Arthur's path much easier.

Locating the Third Landmark in Hogwarts

After finding the rhino skeleton and heading out to the Transfiguration Courtyard, your next destination leads back indoors. Head through the doors behind the dragon fountain and proceed straight up the nearby stairs. As you ascend into the staircase tower, you will encounter the third landmark: a large painting depicting a snowy landscape and a cozy portrait scene.

This portrait serves as the ultimate puzzle location described in Arthur's sketch. Finding this spot confirms you have reached the culmination of the treasure hunt. It stands as a prime example of how Hogwarts Legacy rewards thorough environmental exploration.

Unlocking the Hidden Cache Behind the Painting

To reveal the secret treasure hidden behind the third landmark, you must interact with the painting directly. Cast Accio on the handle attached to the top frame of the portrait. This action triggers a mechanical mechanism, causing the canvas to swing open and reveal a hidden door behind it.

Inside the small wall cavity, you will discover a treasure chest containing a unique cosmetic item. Collecting this reward updates your quest log and allows you to return to Arthur Gaethly. Completing the task grants valuable experience points and adds a stylish new appearance item to your gear collection.

Taking time to learn the castle layout makes future side quests much easier to navigate.

Furthermore, completing early side activities like Cache in the Castle provides a great introduction to the game's puzzle mechanics. Many secret rooms and hidden chests throughout the world use similar environmental interactions. Developing a keen eye for subtle visual clues will serve you well during your entire magical journey.
