3. Gyeonghui Palace
The original name of Gyeong Hui gung was Gyeong Duk Gung, however, it was changed to Gyeong Hui Gung because this name sounds like WonJong. It is also called West palace because it is the one located at the West side among the 5 large palaces. It was named so that it can be differentiated from the East palace which combines both Chang-Duk Gung and Chang-Gyeong Gung. In Gyeong Hui Gung, there were about 100 small and huge buildings such as SOONG JUNG JUN which is the royal audience chamber, JA JUNG JUN(a side room of a palace), and YOONG BOK JUN, HWE SANG JUN which are the King's bedroom. Most of the structures were destroyed during the Japanese invasion time and Gyeong Hui Gung was among them. Kyung Sung middle school was established in the area where Gyeong Hui Gung was. Gyeong Hui Gung is marked as the no. 251 historical place; the original scale was about 70,000 pyeong which is actually three times bigger than the remaining area. Seoul Museum of Art was established in place of Gyeong Hui Gung. Furthermore, since Chongdong Theater and Seoul Museum of History is just nearby, you can enjoy the culture and the arts at the same time.
