This is Nakseonjae Hall.
Nakseonjae was built when King Heonjong received Soonhwagung Kyungbin Kim as his concubine, and used this place as her private living quarter. He sought a modest life, and did not even paint a single piece when building the structure. He was however particularly interested in calligraphy, and hung the writing of his favorite calligrapher, Kim Jeong-Hee, on the signboard.

When you enter the yard, you can see a maru linked to the main building of Nakseonjae, and it almost looks like it is gloating. Clouds decorate the maru, which contains the meaning that this is a world above clouds. There is a symbol of ice near the furnace below, which was put there as a precaution against fire, since the place burns fire for heating.
