The main Tumuli park is an enclosed park space that charged an admission fee. But like most tourist historical attractions in Korea (at least what I’ve experienced so far) – if it’s not free, it’s usually really cheap. In this case, 1500 won (about $1.50CDN). The park area included a nice little walk around the numerous tombs with benches along the way. There was also a nice little pond.
The main attraction of the park was Cheonmachong, a tomb that has been excavated. The inside space shows you what each burial mound consists of – this was really interesting to see. Plus, the amazing air conditioning inside was a nice relief from the humidity. But in all seriousness, inside was a wood chamber that is covered with boulders and earth. The body would have been put into a wooden coffin and burial goods would be buried alongside the coffin. Cheonmachong showed a replica of what the inner tomb would be like. Simply fascinating.
