Enigma

Enigma is a museum housed in a former post office building in Østerbro, near Trianglen metro station, dedicated to the history of communication. The building displays exhibitions exploring postal services, telephone systems, and digital technologies that changed how people connect.

The museum opened in 2017 following a transformation from the Post and Telecommunication Museum with broadened focus on communication methods. The collection traces how message exchange evolved from mail delivery systems to modern digital platforms.

The museum maintains Denmark's largest stamp collection and operates a Learning Lab where students explore technology, innovation, and media literacy education.

The museum is located on Øster Allé and welcomes visitors throughout the week in a converted building that may have narrow passages in certain exhibition areas. Plan time to explore the interactive displays and the basement gaming section at your own pace.

The museum houses one of the world's oldest Enigma cipher machines from World War II alongside interactive digital exhibits. This rare artifact demonstrates how secrecy and technology have been intertwined across decades.
