Långholmen is an island in Central
Stockholm, between Södermalm and Kungsholmen.
Långholmen was once known for having
Sweden’s biggest prison. In 1975, the last prisoner
was released and in May 1989, after two years of renovation
work, it has been reopened as a hotel, hostel and conference
centre. The cells have been transformed into 102 beautiful,
comfortable and functional rooms.
