A lot of modern buildings are in Munjeong Business Center, where a variety of artworks have been installed in collaboration with famous artists. They have created a huge cultural space by embodying Oriental sentiments in the Western style of pop art.
Children will love all the sculptures because those are all about children's play. I recommend you visit the places with your children.
Walk slowly as instructed by this cartridge to appreciate the artworks!
You have to download this Wherigo cartridge here.
Happy Geocaching!
