As mentioned, I was in Buyeo for a week, and while there I took did a cultural tour. ^ ^ Buyeo was the capital of Baekje, a proto-Korean country 18BC to 660AC.
At the fall of Baekje, a thousand (?) court ladies are said to have jumped to their death off a cliff to avoid being captured by the invaders.
This was built as a memorial for the women who killed themselves.
Imagine jumping down here. ^^
