The Hams' Caves, dating back over 10 million years, have been a hidden gem until their discovery in 1905 by speleologist Pedro Caldentey Santandreu (1886-1950). Caldentey stumbled upon these natural wonders while searching for onyx, a precious stone found abundantly in the region.

In 1910, Pedro Caldentey achieved a remarkable feat by generating electricity to illuminate the caves, even before the village of Porto Cristo had access to electric power. Using a water mill, a dynamo, and a water tank, he managed to produce 16 hours of electric current daily, allowing visitors to explore the caves.

Today, visitors can experience the Blue Cave, enhanced with spectacular new blue LED lighting. Here, you can watch the educational documentary “Discovering the Past,” which delves into the history of Majorca, its early inhabitants, the formation of the Hams' Caves, and their discovery.
