What was the former use of Alcatraz Island?

Ive been there! You ride a ferry to Alcatraz, I enjoyed listening to the guide and my brother talking about it,, My brother lived in CA, San Francisco,, The sound those metal bars made as they clamped clang shut,,was a eery (uh oh as I swallow my gum type feeling😳😳The prisoners never was allowed or took any showers in cold water,, so there body wouldn’t be use to cold water, to never be able to swim across,,The coldest winter I ever had was a summer in San Francisco🤔🤗🤗God bless everyone

NormaJean , I agree, they should put the worst of the worst there and then society would be safe at least from them.

TJ SISTA, mine too

Fortress Alcatraz was used as a prison during the American Civil War as well.

It's on my bucket list 😎.
