This fine gallery is the brainchild of Agnes and Karlheinz Essl, collectors of contemporary art from the 20th and 21st centuries. They desired somewhere suitable to showcase their extensive collection, so they built the gallery. Expect to see a plethora of big names: Gerhard Richter, Hermann Nitsch, Georg Baselitz and Elke Krystufek are but a few of the artists on show. The construction itself is the work of Austrian architect Heinz Tesar and incorporates clean white lines, an abundance of natural light and plenty of open space. Entry is free from 7pm to 9pm on Wednesday.
