Alcatraz ("The Rock") packs a dense layer cake of history into 22 acres. Every structure tells a story—military fortress, federal penitentiary, Native occupation site. Here are the key landmarks you'll encounter.
**Oldest operating lighthouse on the U.S. West Coast.** Original 1854 tower replaced by current 84-ft concrete tower (1909) after 1906 earthquake. Still active (white flash 5s). Keeper's house ruins adjacent. *Not open for climbing.*
The **iconic image of Alcatraz**. 336 cells (5×9 ft), 3 tiers. **B & C Blocks** = general population. **D Block** = segregation (24-hr lockdown). **A Block** = rarely used (storage/offices). **Famous cells:** #108 (Machine Gun Kelly), #152 (Birdman Stroud — actually in hospital), #131 (Escape of '62 dummy heads). **Audio tour** (included with ferry) narrated by former guards/inmates.
Central meeting point — **most dangerous room** (knives, crowds). Tear gas canisters mounted overhead (never used). Now houses **"Alcatraz: The Long Walk" exhibit** (photos, artifacts, inmate art). **Christmas menus** posted (roast turkey, cigars — once a year).
Small concrete rectangle, surrounded by 20-ft walls, gun towers at corners. **Inmates got 1 hr/day** (weather permitting). Baseball (soft ball), handball, weightlifting (improvised). **Stunning views:** Golden Gate, SF skyline, Bay Bridge — psychological torture for lifers. **Scene of 1946 "Battle of Alcatraz" shootout.**
Full-service: **operating room, X-ray, lab, pharmacy, dental, psych wards, solitary "bug rooms."** Treated inmates, staff, families. **Al Capone** spent time here (syphilis). **Exhibits** on prison medicine, improvised weapons removed from bodies.
**Luxury amid lockup:** 17 rooms, wraparound porch, gardens (inmate-tended), views of SF. **Three wardens lived here** (Johnston, Swope, Blackwell). Burned during 1969–71 Native Occupation (Indians of All Tribes). **Ruins stabilized; interpretive signs.**
**Staff recreation:** bar, bowling alley (2 lanes), dance floor, library, kitchen. Hosted holiday parties, weddings. **Now exhibits** on daily life of ~60 correctional officers & families who lived on island. **Children took boat to SF schools daily.**
Only via Alcatraz Cruises (Pier 33, SF).** Book weeks ahead. **Night tour** (most atmospheric). **Allow 2.5–3 hrs.** Wear layers; wind is relentless.
Alcatraz isn't one landmark—it's a **preserved total institution**, frozen in 1963. Every corridor echoes with 10,000 inmate stories.
