I which the’d said something about the 75,000 year old relics.
Are they Goryeo, which is medieval times, or Joseon, which would be the dates given?
The middle one looks like the hanja symbol for "ryeo" in Goryeo, but it's hard for a dilettante like me to tell for certain.
The relics go back to as early as 75,000 years ago, ranging from the Paleolithic Era; the Three Kingdoms era (57 BC-AD 668); the Goryeo Dynasty (918-1392); and the Joseon Dynasty (1392-1910).
