The parish church of Marciana, dedicated to Santa
Caterina, it currently has und sixteenth-century aspect with some
eighteenth-century additions. But in the inner of the building,
some structures have been capacities to the light that could belong
to a more ancient sacred building, of medieval age, in occasion
of recent restorations. However is was not found some document that
indicates the existence of it. Sure Marciana it was ancient settlement,
and its history bloomed until the fifteenth century, when it saw
the construction of a fortress to work of the Principles of Piombino,
the Appiani.
