Another place of interest is the parish church of S.S. Giacomo e Quirico, built in the 11th century, was destroyed and rebuilt several times by pirates. Today the external structure is Renaissance while the internal one is decidedly Baroque. There are some precious paintings here, but the most important painting is attributed to Giovanni di San Giovanni Valdarno (1592/1636) and depicts the mystical wedding of Saint Catherine of Alexandria. Leaving the Church of SS. on the right. Giacomo and Quirico, at the end of the street is the 16th century Church of the Pietà. In Rio Elba there is also the Garibaldi Theater, a small theater recently renovated, where the main cultural activities of the municipality are held. The old wash houses with brass spouts are also interesting. In the Canali area there is the Casa del Parco where you can find numerous information on the beauties of the Tuscan Archipelago National Park. Near the ancient "Grassera", a medieval village destroyed by Turkish pirates in 1500, along the road leading to Nisporto and Nisportino, there are the Hermitage of Santa Caterina, a small 16th century sanctuary, and the Orto dei Semplici which preserves a variety of typical Elban plants.

Rio Marina was once considered the iron capital of the island. The mines and the port were used for the excavation and transport of iron ore which, even today, with its shine and classic reddish colour, characterizes the whole town, from the facades of the houses to the beaches, including the same seabed.. Near the last houses of the town there is the Rio Marina mine which reaches up to Monte Giove. Here hematite and pyrite were obtained in abundance. After the closure of the mines (the last one was closed in 1981), the mining activity had to give way to tourism development, transforming Rio Marina into a thriving seaside resort and the buildings that once belonged to the mines into museum structures. Inside the building that once housed the Mining Directorate, there is currently the Museum of Elba Minerals and Mining Art and the historical archive of the mines. Inside the museum the original environments of the mine are recreated and an important collection of samples of minerals and stones from the Island of Elba is preserved. The municipal Mineralogical Museum "Erisia Gennai Tonietti" is also worth a visit, housing over 700 specimens of rare beauty. Of particular historical interest is also the hexagonal tower of the port, built in the mid-16th century by order of Jacopo V Appiani, while the original tower with the clock dates back to 1882, the year of foundation of the maritime municipality and the oratory of San Rocco erected in 1570

Cavo is a seaside resort, touristically equipped, with a sandy beach that reaches up to Capo Castello, where there are the remains of a Roman villa from the first century AD. and a beautiful cliff coast that from Capo Castello reaches Capo della Vita. The small port, in addition to being the closest port for connections to the mainland, is supplied with water and fuel for pleasure boats. Illustrious guest was Giuseppe Garibaldi who in 1849, traveling to the island of Caprera, made a brief stop there. In the small hamlet you can admire the Tonietti Mausoleum, the singular Art Nouveau building that rises among the wild vegetation of the island, designed by the architect Adolfo Coppedè commissioned by the Tonietti family as a burial chapel. The Toniettis were the first concessionaires of the iron mines on the eastern coast of Elba after the unification of Italy.
