Located under the rock wall of Chokseongnu, Jinjuseong Fortress, this rock was called 'Wiam(Dangerous Rock)' before the Japanese invasion of Korea in 1592(Imjinwaeran).

This rock has become famous for Nongae, a woman who committed suicide jumping into Namgang River from this rock, holding a Japanese general to kill him during the Imjinwaeran. After the Imjinwaeran, it was named 'Uiam(Righteous Rock)' in memory of her self-sacrificing spirit.

The top surface of this rock is flat, 3.65m wide and 3.3m long, and rises above the Namgang River.
