Changdeokgung Palace is one of the Five Grand Palaces of the Joseon Dynasty. It was the second royal villa built after the construction of Gyeongbukgung Palace. King Taejong chose to build a new palace at this site, and he set up the Bureau of Palace Construction to create the entire complex. Construction started in 1405 and was completed by 1412. Changdeokgung is the most well preserved of the five Joseon palaces. Its grounds contain a public palace area and a royal family residence. There is also a rear garden with a huge 300-year old tree, a pond, and a pavilion. All of that is set on a hilly site with an area of 58 hectares. The palace is designed in the Far Eastern style, and the architecture seamlessly merges with its landscape to produce an aesthetically pleasing site that is now a UNESCO World Heritage Site.
