I just download Bird's journey story and start to read it, for my long fright to South Africa :), to find acceptable evidence to support the connection.
Durian, I was wondering what you thought about Bird's descriptions of the "Mulberry Palace"?
Seemingly this is Changdeokgung palace, she mentions a pond, located on a hillside, with a fine audience hall, etc. These seem to point more toward Changdeokgung, yet I can find no other example of a palace in Seoul ever being called the "Mulberry Palace".
She mentions Gyeongbok palace by name plenty of times, and this description does not fit. Furthemore, she mentions the newly built palace (Deoksogung), which Gojong built in part for his own safety. So it is not these two palaces for sure. So it is either Changdeokgung, Changyeonggung, or the minor Gyeonghuigung.
