History
Preonzo is first mentioned in 1335 as Prevonzo. In the 14th century, Moleno and Preonzo formed a settlement. In 1335 it became a municipality in the County of Bellinzona. During the first conquest of the Ticino in 1403–22, it was ruled by the cantons of Uri and Obwalden. They granted the villages its statutes and customary rights (Statuti, ordini), although, in contrast to Moleno, it was not incorporated in the Levantine.
The parish church of SS Simone e Giuda was built in 1459. In the 17th century it was rebuilt and then renovated in 1963–66 and 1996–97. It broke away from the Church of S. Vittore in Moleno in 1545. Together with Gnosca and Moleno it was one of the three churches that used the Ambrosian Rite in the County of Bellinzona.
Traditionally, the village economy was based mostly on alpine pasturage and agriculture. However, by 2005, only 13% of jobs were in agriculture, while 56% were in manufacturing. More than three-quarters of workers commuted to Biasca and Bellinzona.

The rockslide of Valegión
The rock wall ("Valegión", "Purscì") at Alpe di Roscioro (or Roscèro) at 1,517 m (4,977 ft) above sea level about 2,000 m (6,600 ft) from the Preonzo industrial park has collapsed several times in the past centuries. In 1702, 1725, and 1747, rock slides and debris destroyed parts of the old town, and boulders have been found over 400 m (1,300 ft) from the base of the slope.
In the 1970s, a small retaining wall for 3,000 m3 (3,900 cu yd) of rock was built in preparation for construction of the motorway in the following decade. In 1998, the industrial park expanded and another, larger retaining wall with a capacity of between 15,000 m3 (20,000 cu yd) and 20,000 m3 (26,000 cu yd) was built. Between 1999 and 2003, a number of sensors were placed on the rock wall to study factors leading up to rock slides.
In 2001, two landslides descended from the "Riale Valegión":
- The first, in June, (between 25,000 m3 (33,000 cu yd) and 28,000 m3 (37,000 cu yd)) filled the retaining walls and flooded the industrial park.
- The second, in July, (20,000 m3 (26,000 cu yd)) was mostly stopped by the retaining walls, but the slide flowed into part of the industrial area.
These events induced the authorities to increase the capacity of the largest retaining wall from 20,000 m3 (26,000 cu yd) to about 70,000 m3 (92,000 cu yd). The retaining wall was completed in the end of 2002. On 7–8 May 2002, about 150,000 m3 (200,000 cu yd) of rock fell over 7 hours during heavy rain from Roscioro. Only a few boulders reached the partly completed retaining wall. During the night of 14–15 May 2012, there was a major rockslide above Preonzo which resulted in no deaths or damaged buildings, but did cause road closures (at intervals even the motorway). About 300,000 m3 (390,000 cu yd) of rock collapsed on 14–15 May with another 500,000 m3 (650,000 cu yd) of rock that could potentially fall in future.
