The Gallery of Young People's Art Works Celje is the only permanent gallery in Slovenia earmarked for young artists up to the age of 20 from all over the world. It is also the only private gallery in Europe, with the only private international competition for art works of young artists in the world from the year 1995 onwards.
The competition, according to the number of participating countries in one year and until now (45 / 85), is one of the ten largest in the world. The collection of art works on the theme "The Horse" includes 45,000 art works from 55 countries and is the largest collection of the sort. There are more than 120,000 art works from 85 countries in the gallery archives.
During this period we have set up 180 exhibitions (70 of them abroad) in 26 countries all over the world (France, Croatia, Serbia, Montenegro, Poland, Slovakia, Hungary, Belarus, Indonesia, USA, Turkey, Argentina, Russia, Bulgaria, Italy, Czech Republic, Bosnia and Herzegovina, Macedonia, India, Iran, Moldova, Romania, Cyprus and Slovenia).
Each month a new exhibition is set up in the gallery. The exhibitions of individual schools are opened by the mayors of their cities and the exhibitions from foreign countries are opened by their ambassadors in Slovenia. Since the year 2000 we have collected all the articles, TV and radio shows about the gallery and its founder. There are over 1000 newspaper articles in 30 languages and 100 TV and radio shows from 15 countries.

"THE WORLD OF ART" magazine was founded in 1995 and is designed for children, young artists and academic artists. It contains information about exhibitions, results, international competitions and other galleries, ex-tempore of painting, sculpturing, graphics and photography. Its readers can be found in 26 countries on all continents. It is sent to many art schools in developing countries for free as a small contribution to their art knowledge and development. In this way, young people in those countries are given an equal opportunity for participating in international competitions and to be awarded for the participating artworks. The magazine represents their window to the world of art and young artists of other countries.
