Leopoldstadt is the 2nd municipal district of Vienna in Austria. As of 1 January 2016, there are 103,233 inhabitants over 19.27 km2 (7 sq mi). It is situated in the heart of the city and, together with Brigittenau, forms a large island surrounded by the Danube Canal and, to the north, the Danube. It is named after Leopold I, Holy Roman Emperor. Due to its relatively high percentage of Jewish inhabitants before the Holocaust, Leopoldstadt gained the nickname Mazzesinsel. This context was a significant aspect for the district twinning with the New York City borough Brooklyn in 2007.
