Angel Island in the San Francisco Bay served as the primary immigration processing center for Asian immigrants to the United States between 1910 and 1940. Detainees, some of whom waited for months or years, endured prison-like conditions and experienced immense hardship. To cope, many carved poems into the walls expressing their suffering, longing to return home, and hopes for eventual success. Today Angel Island is recognized for its historic and cultural significance, with efforts to preserve the poetry and legacy of those who were once detained there.
