Walking along the ancient via that connected Clauzetto and Vito d’Asio, part of the Monte Corona landslide that caused great devastation between these two villages for two months in 1914 is still clearly visible. The landslide damaged several buildings and destroyed about thirty hectares of meadows, fields, vegetable gardens, vineyards and orchards. This was the beginning of the depopulation crisis that would later hit Clauzetto hard. The tragedy was so great that it made the national news and on 12 April 1914 the Domenica del Corriere devoted its front page to the event.
Running water was brought to San Leonardo Valcellina in 1837 thanks to the intuition of a local farmer, Giovanni Antonio Dell’Angelo, known as Pellegrin. Before that there was the “lagoon”, a stagnant and unhealthy pool, fed by the rains, in the centre of the square.
