Alcatraz is a famous prison on Alcatraz Island in San Francisco.It closed down in the early 1900s.But Mother Nature is one criminal this prison cannot catch.
200 years after people: Outside Alcatraz not much has changed, but inside, it's a different story. The bars that once kept criminals inside are long gone. The furniture is also gone.
350 years after people: The sound of crashing echoes through the abandoned city of San Francisco, breaking the peace and quiet. One of the watch towers of Alctraz is starting to collapse. Finally, after 350 years without maintenance, all the watch towers, all at once, collapse onto the surrounding edifice. Now Alcatraz is seen no more.
