French Cultural Village
It was a filming site for famous Korean Drama like Secret Garden and Man from the Stars and also for Running Man, a Korean Variety Show. There are memorabilia from the different Korean Drama in the cultural village.
Saint-Exupery and Little Prince
Aside from the picturesque French village, it is the home for the gallery of the famous French author Antoine Marie Roger De Saint Exupery. 
You can check out the Saint-Exupery Memorial Hall. There are life-size images of Saint-Exupery’s renowned book of Little Prince.
My favorite spot in the cultural village is Fountain Square and the Butterfly Garden which is overlooking the Cheongpyeong Lake.
You can also go inside the different buildings and check out the decorations, art paintings, galleries and also to appreciate the European style houses.
There are special French art performances in the Amphitheater. For more information, you can check the website for the performance times.
There’s a miniature Eiffel Tower of Paris in the cultural village.
