It seems that the name gairo means ‘land that flows’. It is not by chance that the events that tormented this place, starting at the end of the 19th century, precisely due to the instability of the land on which it stands, had a dramatic outcome in October 1951. Today, in ‘old’ Gairo, you can see the ruins of the buildings that have remained tenaciously clinging to the rock of the Trunconi mountain, which dominates the valley of the Pardu rivulet below, with little dirt and cobblestone alleys linked by steps and sloping lanes. In fact, the roads delimited the terraces on which the buildings stood and they are therefore positioned horizontally, on staggered levels, along the slope.
