Palazzina Appiani is a historical building located in Milan, northern Italy. It was built as the entrance hall of the arena at the beginning of the 19th century by the French, who occupied Milan in 1796. Its original function was to be the official gallery and guest residence to host Napoleon's family during his public appearances. It is located in Parco Sempione, the biggest park in the city, which also comprises the Sforza Castle and the Arch of Peace. Adjacent to the Arena Civica, the Palazzina is now entrusted to FAI – Fondo Ambiente Italiano.
