Eight-lady Cave

The sacred cave is a popular stop for those traveling on Road 20 on the way to the Paradise Cave. The women starved to death in 1972 in a rock cave when they were hiding from U.S. raids. U.S. bombs caused an immense 100-ton rock to fall over the only exit of the cave that the women were hiding in. Great efforts to rescue the women were in vain. Soldiers stationed nearby recalled that they heard cries for help resounding from within the cave. The voices were steadily weaker day after day and stopped after the ninth day. In 1996, the remains of the eight women were taken out of the cave for official burial.
