The Lek company (part of Sandoz, a global generics leader), with its tradition of more than 60 years, is also active in the presentation of arts and culture. Located in the entrance hall of its headquarters building, the Lek Gallery has presented contemporary painting or sculpture for more than a decade, organising around 9 exhibitions a year. Presented artists come from Slovenia and the countries where Lek is represented. The programme includes renowned names as well as younger artists and some amateur artists (painters, photographers) who work in Lek. Occasional exhibitions of works from the Lek Collection are also held. On the occasion of the 29th Biennial of Graphic Arts, it featured the works from the renowned "École de Paris", collected by the International Centre of Graphic Arts (MGLC).
With the exhibition of graphics by Slovenian authors called Tribute to the Biennial, the Lek Gallery joined the celebration of the 30th-anniversary edition of the Biennial of Graphic Arts in 2019, as one of most important Slovenian art exhibitions with an international character. The biennial remains the oldest such printmaking exhibition in the world.
