Guam - Angel Santos Park, Continued

When the Japanese occupied Guam, they carved tunnels and caves into the hillsides. Well, they didn't their prisoners of war and the Chamorro, who were in labor camps, dug them out.

Cave Entrance
This is a tunnel entrance where the Japanese stored ammunition and soldiers waited for the American invasion. It looks awfully dark and scary in there, but I guess we are going in.
Tunnel
The tunnels are around six feet high and there is ventilation and wells for fresh water so that many soldiers may stay in here for a very long time.
Cave Entrance
The tunnels all connect together so there are multiple entrances and exits.
