Summary
[edit]DescriptionSan Francisco Trip - October 2010 - Visiting Alcatraz (5085312209).jpg | We visited Alcatraz as part of our trip. The lighthouse at Alcatraz Island is the oldest operating light station on the West Coast of the United States. The original tower was built in 1853. It was replaced with the current tower in 1909, when the current cell house was built on the island. |
