Huge park about the Baekje culture and history. Really nice and interesting. It's only 4000W with the museum and can see and experiment a lot. Take about 3h to see everything but it worth it.
I can experience the palace's inside. and I can make Ceramics. Especially attractive place is 'Kofun Park'. Because here is someone's grave. of course, everthing in here is made. not real :)
