Hollow Knight, a Metroidvania action-adventure game developed by Team Cherry, follows the journey of an unnamed warrior known as the Knight across Hallownest. This kingdom is now in ruins due to a dreadful illness.

As the Knight goes through Hallownest, he will be able to acquire new items, abilities, spells, and charms, allowing him to solve puzzles and explore more of the world.

One of these game items is the Hallownest Seal. According to game history, these items serve as the official emblems of the Pale King and the Five Great Knights.

The Hallownest kingdom’s design incorporates the emblem as well. The following guide will explain where to find the Queen’s Gardens’ Hallownest Seals, which may be found across the entire Hallownest.

There is only one Hallownest Seal in the Queen’s Gardens:

Queen’s Gardens Hallownest Seal

The Hallownest Seal in the Queen’s Gardens can be found on top of a platform in a room in the westernmost part of the area.

In the Queen’s Gardens, the Knight will encounter various enemies. However, the Knight will encounter Oomas, Uomas, Spiny Husks, Fool Eaters, Mossflies, Mantis Petras, Mantis Traitors, and Loodles on the way to the Hallownest Seal in the area.

Before the Knight can go to the Queen’s Gardens and find the Hallownest Seal, the Knight must have the Isma’s Tear ability, which allows the Knight to swim in acid pools, the Mantis Claw ability, which allows the Knight to cling to walls and jump off of them, the Mothwing Cloak ability, which allows the Knight to perform a horizontal dash forward, and the Monarch Wings ability, which allows the Knight to perform a secondary jump in mid-air. With these abilities, getting to the Queen’s Gardens area and finding the Hallownest Seal will be a breeze.

To find the Hallownest Seal in the Queen’s Gardens, this is what the Knight must do (assuming this is the Knight’s first time in the area):

1. From the Bench in the Queen’s Station, head to the right to exit, head to the top using the small platforms in the middle of the room, then take the exit on the left.

After that, continue heading to the left, where the Knight will run into a Mantis Petra, drop down on the gap on the left, then head downwards using the small dropping platforms (be careful not to fall to the thorny vines at the bottom) where the Knight will find another Mantis Petra and another two Mossflies, then head for the exit on the bottom right of the room.
7. Next, head to the right, where there are several stable and dropping platforms with vines filled with thorns on the bottom. Upon getting to the middle of this part of the room, the Knight will be locked in the area, and the Knight must defeat the enemies in the room to continue. Here the Knight will have to defeat three Mantis Petras.
