It's a cute little door. Innocent enough, right?

Be careful where you walk...at least during the war because it could be a trap.

Here's your sign.

Going down...we saw several places to enter the Cuchi Tunnels.

If I remember right, these are cots for the soldiers, perhaps the high-ranking ones.

Here is the tunnel. Sorry for the poor picture. Use your imagination and you might be able to see it. Now imagine being here during the Vietnam War.

Here is the operating room, still in the Cuchi tunnels mind you. They have four levels underground. We only saw the first two.
