This was the 'town of iron' up until the 1960s when mining activities gave way to the development of the tourist industry. However the true 'nature' of this town can still be seen in the red iron ore colour of the houses and on the beach, shaped like an amphitheatre.
It has 1800 inhabitants and became administratively independent from Rio nell'Elba in 1882.
Among the most interesting historical and cultural sites to visit is the Torre dell'Orologio (Clock tower) built on an octagonal plan by Giacomo d'Aragona and in which the clock itself was installed at the end of the 1800s.
The Mineral Museum in the Municipal building is very interesting with over 700 examples of minerals found on Elba. A visit to the Oratory of S. Rocco is a must, built by the Prince of Piombino in the 16th century in the town centre.
There are several excursions that leave from Rio Marina: for instance a trip along the panoramic road of the Porticciolo, to the Torre del Giove or to the Monte Grosso. There are also trips to the islands of Palmaiola, Cerboli and the tiny island of the Topi.
Market day: Monday in the town centre and Wednesday in the village of Cavo.
