Built around 1900, the Karosta Prison was initially used as an infirmary. However for most of the 20th century, it was used as a Nazi and Soviet military prison. It's history was so gruesome, even the solitary confinement room features a cryptic message above the door: ‘izeja no elles’, Latvian for ‘exit from hell’.
The Karosta now serves as a museum/hotel, where guests must sign a release form acknowledging that they will be treated as a prisoner, complete with verbal abuse and physical exercise.
Each room is very simple. You'll get a bed, a small dresser and a toilet - just like the real inmates of the past.
