Sent by Kyunga (South Korea).
The postcard features the main entrance to the Changdeokung Palace in Seoul. It is in the UNESCO World Heritage List since 1997.
One fact about receiving postcards from Postcrossers is that sometimes it arrives a postcard from a very far away place, kike South Korea. By the way: there are only 5 postcrossers in North Korea and it is no easy to visit that country. So I'm afraid I have few chances to get a postcard from there!.
