Palazzo Dall’Armi Marescalchi, Bologna, Baroque palace in Bologna, Italy

Palazzo Dall'Armi Marescalchi is a Baroque palace in central Bologna, rebuilt in 1613 by Floriano Ambrosini. Its main floor rooms keep frescoes by Ludovico Carracci and Guido Reni, and the large oval hall was frescoed by Felice Giani in 1780.

Built in 1466, the palace was rebuilt in 1613 by architect Floriano Ambrosini. The Marescalchi name came from the marriage of Eleonora D'Armi to Senator Vincenzo Marescalchi. In the 1700s gardens and additional land were added, and further reconstruction followed in the 19th century. The palace was damaged by bombing during World War II.

The Marescalchi name entered the palace's history when Eleonora D'Armi married Senator Vincenzo Marescalchi. Since 1961 the building has housed the Soprintendenza per i Beni Ambientali e Architettonici of the Province of Emilia, the regional office for environmental and architectural heritage.

The palace stands in central Bologna at the coordinates 44.49416, 11.33950. Since 1961 it has housed the Soprintendenza per i Beni Ambientali e Architettonici of the Province of Emilia, so it is a working government office rather than a museum open to tourists. It was damaged in the World War II bombardments and later repaired.

Guglielmo Marconi, born in the palace in 1874, is the reason it is often called Palazzo Marconi. The building later housed the Soprintendenza per i Beni Ambientali e Architettonici of the Province of Emilia after the Ministry of the Treasury acquired it in 1961.
