According to Wikipedia: "The annex of the Jewish Museum Vienna documenting the social, cultural and religious lives of Viennese Jews in the Middle Ages is housed in the Misrachi House, on the Judenplatz, the heartland of the city's medieval Jewish community. The exhibition space, opened on 25 October 2000, is smaller than Dorotheergasse, and thoroughly modern in construction, with ample light, polished concrete features and underground corridors that lead the visitor all the way down to 4.5 meters below street level, to the underlying foundations of the medieval synagogue. In recent years, the Judenplatz museum has hosted contemporary art exhibitions with a spiritual or specifically Jewish theme, such as installations by notable Austrian artist Zenita Komad and several photography exhibitions, most recently a photo essay on Vienna's small but thriving Jewish community by Josef Polleross."
