The Slovenian Police Museum held an open day on 18 May to celebrate the 35th International Museum Day marked by museums around the world through various events in mid-May.
The Museum's origins date back to 1920 when the Police directorate in Ljubljana began to compile a police collection following an example of other countries. The Police Museum has served for collecting, documenting, storing, studying and displaying objects concerning crime and criminal justice in Slovenia, the execution of criminal penalties, the development of security system, law enforcement authorities, and the role of the police in Slovenia's independence war.
At first, the collections were available only to professional community as a source of specialist knowledge and became open to the general public after 1991. The Museum has always attracted a lot of interest and welcomed over 40,000 visitors per year. It is a special museum, unique in Slovenia and the second of its kind in the territory of the former Yugoslavia.
