The Gemäldegalerie has temporarily relocated to the Theatermuseum until 2020, but the magnificent array of paintings remains arrestingly engaging. Some of the most important artists in Europe’s long and storied history of creativity are showcased, with masters such as Rubens, Rembrandt and Titian found on the elegant walls. The slightly eccentric ‘Last Judgment’ altarpiece by Hieronymus Bosch might be the main event, dating as it does from the early 1500s. Vienna is an art’s lover’s dream, and the Gemäldegalerie is a definite must-visit.
