Fort Alcatraz History

Part of the Harbor Defense of San Francisco. Initial construction began in 1853 and included gun batteries, a 200' by 100' brick citadel, two barracks buildings and three cell blocks. By 1858, four batteries were virtually complete and armed. The South, North, West and Three Gun batteries contained a total of 73 large guns including eight 10" Columbiads, forty-four 8" Columbiads, six 42 pounder smoothbore cannons and eight 24 pounder howitzers. The fort barracks was completed and the post was garrisoned on 30 Dec 1859.

U.S. Civil War (1861-1865)

The island was a key artillery post guarding San Francisco Bay. By 1861 the fort had 85 cannon and a garrison of 130 men. During the U.S. Civil War [1861-1865], the Army imprisoned deserters, insubordinate soldiers and Confederate sympathizers on the island.

Post U.S. Civil War (1866-1876)

In 1868, the Army established a permanent military prison on Alcatraz that housed a disciplinary barracks for military personnel and later a P.O.W. camp for Spanish-American War prisoners. After the 1906 San Francisco earthquake it was used to temporarily house civilian prisoners from the city jails. In 1907 it reverted back to being a military prison. On 21 Mar 1907, Alcatraz was officially designated as the Western U.S. Military Prison. In 1909, the Army demolished much of the original fort including most of the citadel, and started building a new prison that included the huge concrete main cell block that was completed in 1912.

World War I (1917-1918)

During World War I the post was used to house conscientious objectors. In 1934 the Army turned the post over to the Federal Prison System.
