At the beginning of the 20th century, in Palma de Mallorca there was a spectacular prehistoric ceremony: It's Who. It had about 100 buildings and structures: a shrine, three talayots, a 25-meter cluster, a necropolis, a maze… In the 1960s, there were only a dozen structures left and the last mark was destroyed in 1971, despite being declared a national monument in 1963.

Mallorca was becoming an important tourist centre, giving priority to the construction of Son Sant Joan airport in the area of the site.

On the 50th anniversary of the disaster, UNED Sunday C. Historian Hernandez Jimenez remembers what happened in an article published in Artyhum magazine.
