The Garden of Endless Pillars is a Genshin Impact Domain that you can find north of the Hypostyle Desert, located west of Sumeru's desert region. However, upon paying it a visit for the first time, you'll find that the Domain is locked behind a Pyro Monument puzzle surrounded by Flaming Flowers.
To prepare, make sure to have a character on your team who can apply Pyro, such as Amber. Once you're ready, head to the Garden of Endless Pillars to the left of the Dune of Carouses. You won't see the Domain immediately—follow these steps to make it appear.
How to solve the Flaming Flower Pyro Monument puzzle to unlock the Garden of Endless Pillars Domain in Genshin Impact
The logic behind this puzzle is fairly simple. The Flaming Flowers are blocked by a wall, so you're unable to extinguish or collect them. You must pay attention to the number of Flaming Flowers beside each Pyro Monument, as this determines the order in which they should be activated. There are five Pyro Monuments in total.
With that said, start by activating the Pyro Monument with no Flaming Flowers beside it, located south of the Domain. Once that's done, activate the Pyro Monument with one Flaming Flower beside it, located northeast of the Domain.
Next, activate the Pyro Monument with two Flaming Flowers beside it, located east of the Domain. Then activate the Pyro Monument with three Flaming Flowers beside it, located southwest of the Domain.
Finally, activate the Pyro Monument with four Flaming Flowers beside it, located north of the Domain. If you activated them in the correct order, the stone at the center will break, forcing the Domain building to surface from underground. If you activated the Monuments in the wrong order, you can reset the puzzle by randomly activating them all until they turn off, and try again.
Once you do succeed, make sure to interact with the Domain once to turn it into a Waypoint! Additionally, you can claim an Exquisite Chest as a reward for completing the Pyro Monument puzzle.
