I was lucky that the AirBnB (Lovely Lavinia) that I stayed in was near to one of the palaces - Unhyeongung.
History
Unhyeongung is the home of Emperor Gojong, 26th king of Joseon Dynasty. The earlier buildings were either destroyed or damaged, but some of the construction remains. The remaining structure includes: Norakdang Hall, Noandang Hall, Irodang Hall and Sujiksa.
One of the thing that Korea fasinated me most about Korea is the combination of modern and history in its landscape and the vibrant color combination used in their Hanbok and Royal Palaces.
So Korea's Royal Palaces is a must go for me in my itinerary. If you're interested in Korea Royal Palaces like me, then you definitely have to get the Integrated Palace Tickets.
This ticket costs ₩10,000, which costs cheaper than if you purchase the admission tickets separately and the tickets are valid for 1 months (some says 3 months) after purchase. Tickets can be purchased at any of the following Palaces.
