The Palazzina dei Mulini , also known as Villa dei Mulini , was one of the two residences of Napoleone Bonaparte in Portoferraio during his exile on the island of Elba (4 May 1814 - 26 February 1815 ). It was a residence intended above all for the public life and representation of the emperor in exile, while his private life took place in the nearby Villa of San Martino .
