Gaeun Open Set (문경 가은오픈세트장)

Gaeun Open Set is a filming site located within Mungyeong Ecoworld. Through in-depth historical research, it realistically recreates the city in the old days, making it an important location for TV series and history education. There are a total of three filming locations. The first filming location has palaces, including Goguryeo Palace, thatched-roof houses, inns, and a grand gate of actual size. It is known as the filming location for various dramas such as "The King of Legend (2010)," "Ja Myung Go (2009)," "Yeon Gaesomun (2006)," and "Strongest Chil Woo (2008)." It is still popular as a filming location for many other dramas. Also located within Mungyeong Ecoworld is the Coal Museum, so many tourists visit them together. It is possible to travel from the Coal Museum to the first filming location by riding the monorail, which runs every 15 minutes.
