Saipan, in the Northern Mariana Islands, was part of the Japanese Empire for 30 years, an outpost populated by both military personnel and civilians. Most of what the Japanese built on the island was destroyed in June-July 1944, during one of the major battles of World War II. The concrete structures that survived remain intact today, raw reminders of the past. These include a jail, lighthouse and hospital, as well as numerous military bunkers and shelters. This collection of photographs looks at these survivors, wondering what stories could be told "If This Concrete Could Talk."
