The Palazzina dei Mulini is most closely associated with the ten months Napoleon Bonaparte spent as sovereign of Elba. The house began as a modest residence built in 1724 near old windmills on the heights above Portoferraio. Its position was strategic as well as picturesque: from the terraces one could watch the harbor, the Tuscan coast, and the shipping lanes that linked the island to Europe. After Napoleon abdicated in April 1814 under the Treaty of Fontainebleau, the victorious powers allowed him to retain the imperial title and rule Elba. He arrived at Portoferraio on 4 May and chose the Palazzina as his principal urban residence.

Napoleon ordered the building enlarged and reorganized for court life. Local structures were joined, rooms were redecorated, and the garden was reshaped to create a residence suited to an emperor whose realm now contained only a small Mediterranean island. The household included French officers and servants, while Napoleon’s mother, Letizia, and his sister Pauline became part of the island’s social world. His wife, Marie Louise, and their son did not join him. The rooms functioned as council chamber, library, reception space, and private apartment, making the villa the administrative center of his miniature state.

Exile at the Mulini was not inactivity. Napoleon inspected mines and roads, reorganized finances, encouraged agriculture, issued regulations, and strengthened defenses. He adopted a new flag for Elba and maintained a small army and navy. Audiences, dinners, theatrical performances, and official ceremonies preserved the forms of imperial government, even as foreign agents monitored him and money promised under the Fontainebleau settlement failed to arrive reliably. From the residence he received news of discontent in France and of disagreements among the Allied powers meeting at Vienna. These reports helped convince him that a return might succeed.

On 26 February 1815 Napoleon secretly left Elba aboard the brig Inconstant. His departure from nearby Portoferraio began the Hundred Days, culminating in his return to Paris, defeat at Waterloo, and final exile to Saint Helena. The Palazzina was consequently transformed from a working palace into a memorial of the brief Elban interlude between two continental dramas. Later owners and authorities preserved surviving furniture, portraits, books, and objects connected with the imperial household, although the rooms inevitably changed after Napoleon’s departure.

Today the Palazzina dei Mulini forms part of Italy’s National Museum of the Napoleonic Residences, together with the country residence at San Martino. Its significance lies in the contrast between scale and ambition. Here a deposed ruler continued to govern, staged sovereignty, and planned his political return within sight of the sea. The villa’s terraces and relatively intimate rooms illuminate an episode often reduced to a prelude: Elba was a functioning principality, and the decisions made at the Mulini directly reopened the Napoleonic Wars in 1815.

The residence also reveals how quickly material culture can be recruited to political memory. Rooms have been reconstructed from inventories, surviving objects, and later acquisitions, so not every furnishing remained exactly where Napoleon used it. Even so, the relationship between harbor, council rooms, library, and garden helps recover the practical setting in which exile became government and government became preparation for escape.
