Where the Barranco del Agua meets the Atlantic in northeastern La Palma, a humble stone structure recalls centuries of island tradition. The Horno de la Cal de San Andrés is a preserved lime kiln that once played a vital role in Canarian construction, producing the essential material for building across the archipelago.

Set beside an old coastal landing, this heritage site rewards those who venture down the short coastal path. The restored kiln stands against the deep blue ocean, its weathered stones telling stories of labor and craftsmanship. When Atlantic swells roll in, the setting transforms into a dramatic natural theatre—though visitors should approach cautiously during rough seas.

San Andrés, recognized as the oldest neighborhood in Los Sauces municipality, offers this quiet corner to those seeking authentic heritage. While restoration of the surrounding walkway remains incomplete, the site maintains an unpretentious charm appreciated by travelers interested in industrial archaeology and local history. It's a genuine encounter with Canarian working life, far removed from typical tourist circuits.
