Grassalkovich Palace, Vienna, Classicist palace in Leopoldstadt, Vienna, Austria

Grassalkovich Palace is a three-storey Neoclassical building on Obere Augartenstraße in Leopoldstadt. A three-axis central riser with giant Ionic pilasters divides the facade, topped by a mansard hipped roof with attic balustrade. The central field bears the princely coat of arms with the initials M. T., and a balcony with wrought-iron grille rests on four Tuscan columns above the basket-arch portal.

Prince Anton Grassalkovich II bought the plot on today's Obere Augartenstraße in 1789 and began converting a single-storey building erected by Johann Georg Mayer from 1780. The palace was finished shortly before the prince's death in 1794; his son Antal III sold it in 1796 to pay debts. The city acquired the dilapidated building in 1975, and from 1991 to 2014 it housed the Vienna Tourist Board.

The palace is named after Prince Anton Grassalkovics II, who bought the plot in 1789 and began converting the existing single-storey building. The Grassalkovich family were Hungarian nobility; Anton's father had been Maria Theresa's finance minister. The building later housed the Almdudler drinks firm and from 1991 to 2014 the Vienna Tourist Board.

The palace is located in Leopoldstadt and is easily accessible by public transportation, particularly via the Taborstraße stop. A short walk from Praterstern station will bring you to the site.

The princely coat of arms on the central risalit bears the initials M. T., which led to the popular but incorrect name "Maria-Theresia-Schlössl". The initials actually refer to Anton Grassalkovich's wife, Mária Terézia Esterházy.
