Museum was reopened in 2009 and since 2011 Moderna galerija has two venues. One is this one - The Museum of Modern Art - and another is Museum of Contemporary Art Metelkova (+MSUM), near the alternative place Metelkova Mesto.
Great place with great art and English descriptions of the exhibitions (and even website)!
The Modern Art Museum has been closed for renovation as of March 4, 2007 and is scheduled to reopen 'sometime next year.'
