My wife is reading this book. I glanced at it and asked her if it mentioned where the photo on the front cover was taken. She searched and found no reference (Korean books don't tend to label every photo), I said it reminded me of Chang Gyeong Palace in Seoul and So opened my laptop and found in Picasa a photo I had taken of the exact same piece of wall in Jongmyo Temple (37.575 N 126.993 E). We compared them and could match each stone exactly. I was pretty impressed with my identification skills, now if only there was a way in which I could use these skills.
