Historical Information:

  • The name of this lighthouse is derived from "alcatraces" the Spanish word for pelican. However, this island is best known as the home of Al Capone and other notorious criminals. A federal penitentiary is also on the island. This light is the oldest major navigational light on the West Coast. For over 50 years, the lighthouse survived prison breakouts, riots and burning.
  • 1906: The great San Francisco earthquake of 1906 severely damaged the original lighthouse.
  • 1963: The light was automated in 1963.
  • 2000: The lighthouse is now a museum and can be toured.
