Fantastic building, some really interesting art from modern Slovenian art history. The staff are young, welcoming and smiley which made us feel happy. We visited on the first Sunday of the month so entrance was free. To be honest the air con in the building was a welcome rest from the intense heat outside so made us enjoy the gallery even more. Lovely sculptures outside the main entrance too. Close to the Tivoli Park which we recommend visiting whilst this side of town.
