OK we were lucky as we had a guide who works there show us around and explain things to us but even without it's marvelous. It stands in a park full of beautiful trees and you hear the sounds of traditional Korean music.
A very interesting archeological site showing how the Silla rulers were buried and the high quality of their gold work, similar in quality to things that I saw in Xian, China. From the 700's time period.
It is quick stop to cover the tomb and the capstone carved with dragons is supported by tortoise. The grass covered mound is typical for the era of King Muyeol and there are a bunch of these spread in the vicinity of this attraction.
