Went to visit Changdeokgung Palace when I was in Seoul. It was a really pretty palace although I've seen some other similar palace in Japan and China.
Missed the secret garden because it was closed, I guess otherwise the garden should be beautiful especially in spring time. I heard a lot of good things about the garden, too bad didn't see it.
Still the architecture of the palace itself is worth a visit, plus the weather was just great that day, here are some photos I took.
