==Geography== In Roman times, the island was named Planasia (plain) because of its flatness – its highest point stands at above sea level. It is a triangular-shaped land mass south-west of Elba and is a frazione of the municipality of Campo nell'Elba. Pianosa is the fifth biggest island of the Tuscan Archipelago and the only one to be formed out of sedimentary rock of the Neogene and Quaternary; such fossils as echinoderms, mollusca and bryozoa of the Pliocene are frequently found.
