Under the earthworks
You can find plenty of holes in the ground around San Francisco’s Golden Gate Bridge; they are the remnants of earthworks constructed during the 1850s — part of the same work that transformed the island of Alcatraz into a fort. I especially like this tunnel because, being short, I only have to tilt my head slightly to the side on entering the west end while everybody else has to stoop!
