Leopold Museum, which has the biggest collection of Egon Schiele's works. Egon Schiele was…read moreinteresting. I did not know he was such a narcissistic twat until he went off to WWI and was humbled and matured by the soldiers he met. He really loved his wife, Edith, though who's to say if he would have stayed faithful if they both lived to old age. I had no idea he died at age 28, and he and his wife died within days of each other, and he died on Halloween 1918.
There's a painting by Klimt I wanted to see, Death and Life, but unfortunately two of their floors were closed for some renovations, so I was disappointed that I was unable to view it during my visit to Vienna.
Very easy to find in MuseumsQuartier, a short walk from Hofburg Palace.
