Military prison under construction on Alcatraz.

In 1909 the U.S. Army began construction on the largest reinforced concrete structure in the world - a new military prison necessary because of a large influx of U.S. soldiers convicted of crimes in the Philippines. This building would become the famous U.S. Penitentiary Alcatraz in 1934.
