It may surprise some people to learn that kings of the Choson Dynasty had to work, @slowwalker - it wasn't just a ceremonial role.

The presence of the sundial before the king's throne emphasized how important time was in an agrarian society - seed time and harvest.

It's also interesting to find the king's living quarters were humble and not elaborately adorned.

Since the king stayed at the palace year round it made sense that certain areas would need to be heated, and of course the preferred method was underfloor heating as opposed to open fireplaces in king's castles in the west.

Underfloor heating is a superior and efficient way of maintaining a comfortable living space, and although it seems quite modern it actually was used as far back as the bronze age.

The photos of the lotus ceiling were stunning as were the photos of the spring room and fall room.

Another entertaining and very informative post, my friend.
