Hagåtña Tunnels

Cut into the limestone cliff at what's now Angel Santos Memorial Park in Hagatna — wartime Agana, the occupied capital — are tunnels the Japanese dug in anticipation of the American return. Guampedia's monuments map records that they were likely meant for storage and air-raid shelter, and that they were built by forced labor: CHamoru, Okinawan, and Korean workers. Nearby in the same cliff face stands the concrete communications bunker the Japanese poured into the rock, its entrances shielded by oil drums filled with concrete — the drums long rusted away, leaving their molds like fossils.

The tunnels hold a specific documented horror. CHamorus accused of aiding George Tweed — the American radioman who hid from the Japanese for the entire occupation — were held in these caves and questioned. The men were led into the jungle and executed; the women, ordered to remain in the tunnel, were executed too.
