A beautiful peasant girl, named Alda, was working in the fields near the monastery, she came to the Sacra to pray against the evils of war; unfortunately, she was ambushed by enemy soldiers. She tried to escape their assault looking for shelter in the monastery but the doors of the monastery were locked. She found herself trapped at the top of a high tower, overlooking the valley from the steep mountain. Left with no other choice but to throw herself into the ravine she invoked the help of St. Michael and the Virgin. She miraculously survived because some angels helped her land unhurt at the bottom of the precipice.
Out of vanity she recklessy tested the angels with a second leap believing she would be able to repeat her flight in front of the unbelieving villagers. Unfortunately as miracles never happen twice, she met her fate at the bottom of the rocks below. A proverb says that the biggest part that remained intact of Alda’s body was the ear. The Tower of the Beautiful Alda, takes its name from this legend.
