A Visionary in North Mallorca: The Adan Diehl Story
In 1929, in a world shaken by crisis, an Argentinian humanist named Adán Diehl saw possibility where others saw wild nature. He traveled to one of the most remote corners of North Mallorca, the dramatic Cap de Formentor, and decided this coastline should become a retreat for culture and contemplation.
Surrounded by a lush enclave of Mediterranean forest and overlooking a turquoise bay, now part of a 1,200-hectare protected park, the Hotel Formentor was born from a mix of intuition, determination, and perhaps a bit of stubbornness.
Diehl believed that true luxury came from preserving the landscape and the essence of this precious Mallorca’s corner.
Actually, this conviction didn't just build a hotel, it defined the blueprint for exclusive properties in Formentor today: privacy above all else.
