Torre degli Appiani, Coastal defense tower in Marciana Marina, Italy

Torre degli Appiani is a circular stone tower at the western end of Marciana Marina harbor, rising from a truncated-cone scarp base separated from the upper shaft by a continuous cordon. An external stair ramp leads to the raised entrance, above which a three-tier machicolation with blind arches projects from the top terrace. Arrow slits open in several parts of the walls.

The structure was built in the second half of the 16th century as a coastal defense post. It remained under the control of the Principality of Piombino until that rule ended in 1815.

The tower's name comes from the Appiani family, lords of Piombino and Elba, though the sources record that in the 16th century it was called Torre della Novaglia, after the coastal plain nearby, from Latin novalia, fallow fields. Since 2005 the site has given its name to the Premio Letterario La Tore isola d'Elba, a literary prize that has passed its twentieth edition.

The tower sits directly on the harbor and is easily reached on foot while walking through the marina. Location by the water means weather and tides can affect how accessible the surrounding area feels.

The tower was originally called Torre della Novaglia, named after the Latin word for fallow land that once surrounded it. Later it became the home of writer Raffaello Brignetti before a citizens campaign led to it returning to state ownership.
