The Palazzo Grassi is Gothic-style, 13th-century palace located on Via Marsala #14 in Bologna, region of Emilia Romagna, Italy.
The palace in 2015 houses the Circolo Ufficiali dell'Esercito, a private Officer's club.
In 1478, the family was honored with the title of Conti Palatini del Sacro Romano Impero by Frederick III, Holy Roman Emperor.
It underwent a number of renovations, with the latest in the 20th century, and in 1935 it became the home of the Circolo club.
Inside the courtyard are intaglio works by Properzia de Rossi and a 16th-century terracotta depicting a Madonna with Child.
