Prehistoric funerary structure
This has become one of the icons of Menorca. The structure is a collective tomb where they've found the remains of hundreds of inhabitants as well as funerary objects and offerings.
Legend has it that there was a princess on the island and there were two giants competing for her hand in marriage. They decided that the first to complete a building would be the suitor. One chose to build a well and the other a tomb. Right when the giant was at the point of completing the tomb, he heard the other giant yell “water,” an indication that he’d finished the well. In a bout of fury, the giant took the last stone he was about the place (the one missing on top) and used it to exact his revenge on his winning opponent.
