From the Seokguram Grotto we headed back into town and strolled through Tumuli Park. The tumulis are grassy hills that enclose tombs built for the Shilla monarchs in the 5th century AD. It’s a very pleasant park, with lots of trees, and some small ponds. All the paths are clearly marked, and there’s piped in music to complete the experience. One of the tombs, Cheonmachong, is open to the public and you can go inside and see how the tombs were made and see replicas of the treasures they found inside (the real things are now at the museum which is closed Monday 🙁 ).
