The Torre de Cala Pi is one of three coastal defense towers in the municipality of Llucmajor, together with the Torre de Cap Blanc and the Torre de s’Estelella, and is one of 45 ancient torres on Mallorca’s coastline.
The Torre de Cala Pi guards the entrance to the cove of Cala Pi and stands at about 19.5 m above sea level. The tower was built after several attacks by the Ottoman Turks in 1543 and was completed in 1663. To my knowledge, the tower was never successfully conquered, not by pirates or Maurish marauders, anyway.
