I got Seoul
I braved the subway system and found my way to an area called Gyeongbokgung. Gyeongbokgung is the location of Joseon Dynasty royal palace, built in 1395 by King Taejong. The Gyeongbokgung palace was sacked and burned by the Japanese in 1592 and laid in ruin for nearly 300 years.Â
The palace was restored in 1868 and consists of buildings for the king quaters, government officials, royal family, and garden. Below is a photo of the large front gate of the palace.

There is a changing of the guard ceremony every hour. You can watch this for free and it lasts about 15 minutes and is announced in Korea, English, and Mandarin.  I took the video below with my digital camera .

You can buy an admission ticket for about $3USD. Make sure to ask about the times for the English guided tour.  I think they are offered on hour intervals at 1/2 past.
If I understood the guide correctly, this is the largest two story outdoor pavillion in Korea.  Its called Gyeonghoeru and was used for royal banquets.

This a small palace named Geoncheonggung within the grounds of Gyeongbokgung palace. It was a meeting place for the king and his court.Â

I highly recommend visiting Gyeongbokgung palace. Its easy to reach by subway, adminision is only $3, includes a guided tour in english, plus entrance to the nearby Korea National Folk Museum is included.   More information is available at http://gbg.cha.go.kr
