This is in Insadong, Seoul, Korea, correct? I went on this tour too. It wasn't clear if it was just one queen or all queens, but I remember the guide saying that once she entered the palace walls, she rarely went out. I too, felt her loneliness, as if it had permeated the walls.

And if I remember correctly, it wasn't King Sejong's wife? A later king's? Who was described by the guide as being so diligent, taking his job so seriously that his health suffered, leading to an early death?
