The well temple is the highest architectural expression of the Nuraghic civilisation dating back to around 3000 years ago. However, it seems to be built today with its square boulders perfectly embedded with perfect geometry. Located near Paulilatino, it is the most representative sacred well of the island where stories, legends, and truths are intertwined. But there is something that not everyone knows, a series of incredible events that regularly occur here like the autumnal and vernal equinox, in September from 21st to 23rd at 12.00 and in March from 18th to 21st at 11.00 on the occasion of the equinoxes the sun perfectly lights up the bottom of the well through the stairwell, also every 18.6 years, during the period of greater lunistice, the moonlight reaches the mirror of water reflecting perpendicularly through the hole of about 30 cm of the tholos room.
