Monteverdi Marittimo
Is on the south side of the part of Tuscany called “Colline Metallifere”. The town was founded during the medieval period when on the site the Abbey of “san Pietro in Pozzuolo” was founded. Around this abbey in fact many people became to Gather together and so a new town was born.
Afterward in the neighbourhood of the abbey a castle was built, which in XII century was under the protection of the city of Volterra. In the same period the monks of the abbey submitted to the city of Massa Marittima. Only in the middle of the same century the monks of the abbey joined the submission to the city of Monteverdi Marittimo, posing the abbey under Volterra jurisdiction. Among the most popular monuments of the city there are the church of “Sant’Andrea”, the oratory of “Santissimo Sacramento”, the castle and the rest of the medieval fortification. The most popular feast is the “Sant’Andrea” feast which is on the 30th of November every year in honour of the patron saint.
The town of Monteverdi Marittimo has a medieval look, thanks to the castle and the rests of medieval fortification preserved.The castle, from high medieval origin, has a circular form and is mainly original.
In the heart of the city centre you can find “sant’Andrea” church built in the 14th century characterized by its stone front and its multi- colour clay sculptures. Not very far from the city centre you can find the ruins of “San Pietro in Palazzuolo” abbey; it is still possible to recognise the fundamental structure of the religious building with the apse, the cloister and the belfry.
Sassetta e Suvereto
At the slopes of the Colline Metallifere in the direction of the sea finds you will find the romantic mountain villages Sassetta and Suvereto, which are about 14 km apart. In the midst of chestnut forests appears Sassetta (340 m above the sea) at a rock slope. This pictorial village is such as nice as a “strain” place, as all lanes lead downhill and consequently also again uphill.
Suvereto was created around the year 1000. By the Porta alla Silici, the well received pisan city wall from the 14. Century, one arrives the upper city towered above by the ruin of the old castle with the pretty Piazza Gramsci. 
Castagneto Carducci
A mountain village as from the picture book. The local centre developed in concentric circles around the – in the 11. Century bricked - Castello of the counts della Gherardesca, before Castagneto Marittimo itself expanded in the 18. Century towards the west. Only since 1907 the place is called Castagneto Carducci after Giosuè Carducci (1836 - 1907), the Nobel prize winner and “poet of the new Italy”, who spent here and in Bolgheri his youth. From the small park of the Piazzale Belvedere 200 m above the sea one has a marvelous view over the hill country and the coast.
Bolgheri
A long and straight avenue of cypresses, the probably most beautiful and the longest in Tuscany, leads from the via Arelia up to Bolgheri. The village is put on like a fortress, half village, half feudal seat of the counts Gherardesca from the 16. to 18. Century. Bolgheri is -due to its since 200 years nearly unchanged built volumes - a genuine rare piece. A rare piece and world well-known is also the Cabernet wine Sassicaia originating from Bolgheri, the best red wine of Italy.
Marina di Castagneto Carducci
Next to a thick pine wood, you can visit Castagneto Carducci marine. It developed in the Fifties near a 17th century fortress, which was built by the Lorena to fortify and improve the defence of the coast.

Biancane natural park is a natural area nearby Monterotondo Marittimo (Grosseto) where you can find the so called „Biancane“, one at the many geothermal places whitch characterize the border betwen Pisa and Grosseto provinces. You can observe various types of geothermal expressions like shower heads, vapor spins from the gound, termales.
The name come from the color of the rocks: in fact the emissions of sulfuric hydrogen cause a chemical reaction transforming limestome into plaster.
Vapor come from the fractures in the ground at a temperature at 100° C and it consists fror the 95% at water vapore. The other 5% is consisting at carbon dioxite, methane, ammonia and hydrogen sulfide which is responsible at the characteristic smeu at rotten eggs.
Nearby the fractures on the ground you can find sulfur crystallizations. The presence of hydrogen sulfide causes on intense acidification of the ground and the powerful chemical aggression of same components of the geothermal fluids produces a feashy ground whitening.
All rocks have been modified from the circulation of geothermal fluids. The most important alterations are the disappearance of the original colors and variations in the chemical composition.
Geothermal Wells
Biancane site is characterized by the presence of geothermal welles from which very higt temperature vapor come out. This vapor is carried to the geothermal power plant on the west side of the site for the production of electricity (10 mw power).
The vapor is sent directly to the turbines and later it is condensed and purified from the non-condesable gases. Condesate water is cooled att end pumped into the ground again.
The production of electricity at an industrial level in Monterotondo Marittimo started in 1916, the 4 geothermic power plants of Monterotondo Marittimo municipality arc able to cover the 70% of the entire energy requirements of Grosseto province through the exploitation of the from geothermal source vapor coming from the geothermal wells.
