Karlsplatz in Vienna’s Fourth District, bordering the Inner District, is especially festive today through 8 p.m. What is being celebrated is Karlstag, which is basically a Karlsplatz openhouse. The visitors can storm the Secession and other museums in the vicinity and stay for longer hours. Best of all the entrance and tour guide are for free.
Karlstag also features a flea market, outside pubs and bars, workshops, and a program just for children at the Wien Museum called “Kinder Wirtshaft,” where the kids can roleplay as waiters serving customers. This correlates with the museum’s current exhibition, “Im Wirtshaus: Eine Geschichte der Wiener Geselligkeit,” a history of the Viennese pubs and their way of life.
