Napoleonic Museum of the Misericordia

Tucked inside a 17th-century church in Portoferraio, this small museum packs a surprising punch — it holds Napoleon's death mask alongside historic documents, artifacts, and relics from his years of exile on Elba. Entry costs just €1, making it one of the most unexpectedly rewarding stops on the island. The church itself, built in 1677, also houses the relics of Saint Cristino, patron saint of Portoferraio, so you're getting two layers of history in one visit.
