Guided tours to the Geothermal Museum in Larderello

The Larderello Geothermal Museum, founded in the late 1950s, is on the ground floor of Palazzo de’ Larderel. Not far away is the demonstration wellhead: drilled in 1956, the well is 740 metres deep, has a diameter of 9⅝ inches, and a flow rate of 15 tonnes. 

The demonstration vent is open all year round and on Thursdays in summer: The Museum offers a guided tour every day (except Mondays) through the building’s galleries, as well as the model room and the indoor lagoon. Every Thursday in July and August at 4.00 pm: ‘Geothermal Thursdays’ – a guided tour of the Museum, a hike to the Sasso Pisano Fumaroles Park and a tasting session.


A multimedia museum: The exhibition tells the story of geothermal energy, illustrating exploration and drilling techniques through models. A multimedia museum particularly well-suited to understanding the geothermal phenomenon and its industrial developments.

The tour takes visitors through ten rooms illustrating the origins of geothermal energy, from the establishment of the first chemical factory, through experimentation with energy production—first mechanical, then thermal and electrical—right up to modern power stations. Outside, amidst the modern facilities, the remains of 19th-century buildings can be seen, such as the covered reservoir near the visitor reception area
