The gardens of Alcatraz.

Did You Know?
The abundant plant life found on Alcatraz today is not quite “natural” – originally the island was a barren, wind swept, bird guano covered piece of sandstone rock. Soil and plants were introduced by the U.S. Army as they built the first U.S. fort on the West Coast, beginning in the 1850s.
