This sign is located at San Francisco's Pier 33.
Located near the ferries that bring visitors to Alcatraz, this sign accompanies a large replica of Alcatraz Island and its buildings.
It has a few old photos and reads:
"GUARDHOUSE & SALLYPORT COMPLEX
Built in 1857, the guardhouse is the oldest building
on the island. The first line of defense against enemy
landing parties, it could only be entered by crossing a
drawbridge over a 15-foot deep dry moat. Two gun ports
for 24-pound howitzers flanked the entrance, and firing
positions for riflemen capped the roof. Alcatraz's defenses
were never tested in battle. Instead, the Guardhouse's
basement served as a prison for troublesome army soldiers.
Later uses included a military prison, library, theater,
and schoolhouse."
