Apponyi Palace is a prominent monument in Bratislava, Slovakia, adjacent to the Old Town Hall.

It was acquired in 1867 from the Apponyis by the Bratislava municipality, which subsequently added its arms on the cartouche above the street doorway.

The first floor is the representative piano nobile with preserved rococo-classical interior decorations.

The second floor was used as private quarters by the Apponyi family, with less high ceilings and less elaborate decorations.

The attic was used for accommodation from the 18th century until the first half of the 19th century (it was common for visitors to coronations and other major events to sleep in the attics of townhouses and palaces of the noble).
