The Linguella Museum occupies a long single-storey building on the spit of land that closes off the eastern side of Portoferraio's harbour — originally a Medici saltpetre store, later a salt warehouse, now a museum of the archaeology of Elba. The collection is modest but well-presented and covers everything from prehistoric flint tools through Roman amphorae raised from local wrecks to medieval ceramics from the Pisan and Genoese periods.
The standout items are the Roman material: amphora cargoes from shipwrecks off Elba and the surrounding Tuscan Archipelago, mosaics from local villas, and stamped tiles from the kilns at Le Grotte (just east of town). The building next door encloses the remains of a Roman patrician villa, with mosaic floors visible beneath glass panels. Allow about 45 minutes. Easy to combine with a walk out to the Torre della Linguella at the tip of the spit.
