Have you ever noticed the large bronze basin in a Korean royal palace? It is called a Deu-meu (드므).

Many people think it was simply a water container for fighting fires. However, to the people of the Joseon Dynasty, it also held a deeper symbolic meaning.

In the past, people believed that Hwama (火魔), the fire demon believed to cause fires, would flee in fear when it saw its own reflection in the still water of the Deume. For this reason, these large basins were always kept filled with water and placed in front of important palace buildings where the king resided, both to help prevent fires and to protect the palace from evil.

The Deu-meu also served a practical purpose by storing water that could be used in the early stages of a fire. But for the people of Joseon, water was more than a firefighting resource—it was a symbol of protection, believed to drive away misfortune and safeguard the royal family.

At night, the calm surface of the water reflects the surrounding palace buildings.

People believed that this quiet mirror-like surface could reveal and repel even the unseen forces of disaster.

The next time you visit a Korean palace, take a moment to look into a Deu-meu.

You may find that it reflects not only the palace around you, but also the hopes, beliefs, and imagination of the people who lived here over 600 years ago.
