Why these sites survived instead of being demolished
Most former prisons are torn down once decommissioned, since the buildings are expensive to maintain and carry a grim public image. The ones that survive as museums usually do so because of a specific historical significance β a famous escape, a role in a political movement, or an architectural innovation β that made preservation groups or governments decide the story was worth telling.
The tone varies a lot by site
Some of these museums lean into dark tourism, with tours built around escape stories or ghost sightings, while others, like Robben Island, are run primarily as memorials to political struggle and human rights. It is worth knowing which framing a site uses before visiting, since the experience differs considerably.
Frequently Asked Questions
Can you actually go inside the cells at these museums?
At most of these sites, yes β self-guided or docent-led tours typically take visitors into cell blocks, and some, like Alcatraz, offer audio tours narrated by former guards or inmates. A few restricted areas may be closed off for preservation reasons.
Do these sites need to be booked in advance?
Popular ones like Alcatraz sell out days or weeks ahead during peak season since visitor numbers are capped by ferry capacity, so booking online in advance is strongly recommended rather than assuming walk-up tickets will be available.
