Roznovanu Palace, City hall in Iași, Romania

Roznovanu Palace is a neoclassical building in central Iași, rebuilt between 1830 and 1833 by architect Johann Freywald for the Rosetti-Roznovanu family. Its exterior once featured statues, and the interior has frescoes. Since 1970 it has housed Iași City Hall.

Built in the second half of the 18th century, the palace was rebuilt between 1830 and 1833 by Iordache Ruset-Roznovanu, with restoration by architect Johann Freywald. It remained the Rosetti-Roznovanu family residence until 1891, when it was sold to the state. In 1916–1918 it housed ministries of the Romanian government relocated from Bucharest, and King Ferdinand I's office occupied the room now used by the mayor.

The palace was the residence of the Rosetti-Roznovanu family, among the most influential in Moldavian politics, until it was sold to the state in 1891. Its salons received Carol I, Natalia Keșcu (later Queen of Serbia) and soprano Hariclea Darclée. In 1866 the family, backed by Russian political circles, plotted to place Nunuța Roznovanu on the Moldavian throne; the plan failed.

The building sits in central Iași and is easily found by its prominent position and neoclassical design. Note that some interior spaces may have restricted access since municipal government operations continue inside.

In 1918 the palace's current council chamber hosted a session of Romania's War Council, while the ground floor housed a civilian hospital run by the American Red Cross mission. King Ferdinand I kept his office in the room now used by the mayor.
