This event is traditionally held on the last Friday in January and it tries to implement activities which deal with the perception of museums as institutions of the Croatian identity.
Over the years, Museum Night has paid tribute to many influential figures who had an important role in Croatian history.
The main topic of this year's event is "Music, Music Greats and Their Influence on the Society".
Museums in more than 110 cities and towns across the country as well as some other cultural institutions will be open from 6 pm until 1 am.
Museum Night encourages activities that develop curiosity as a motive for visiting museums, but it also provides a space for fun and meaningful leisure activities. It was held for the first time in 2005 in Zagreb as a pilot project with only 6 museums participating.
Zagreb is also known as the capital with the greatest number of museums per capita in the world.
