Blenio is a municipality of the district of Blenio, in the canton of Ticino, Switzerland.
Blenio was created on 22 October 2006 when it incorporated the formerly autonomous municipalities of Aquila, Campo Blenio, Ghirone, Olivone and Torre of the upper Blenio valley.
A legal challenge to the merger was raised by Aquila, but was rejected by the Federal Court on 18 April 2006.
History
Aquila is first mentioned in 1196 as Aquili. Ghirone is first mentioned in 1200 as Agairono. Olivone is first mentioned in 1193 as Alivoni, then in 1205 it was mentioned as Orivono. In Romansh it was known as Luorscha.
Aquila
Around 1200, the settlement of Ghirone belonged Aquila. The present borders were established in 1853 with the final separation of the two municipalities. The parish church of San Vittore was built in 1213. It was rebuilt in 1728–30. One important source of income for the village came from money sent back by emigrants from the village to other European countries (often as chocolate makers, waiters, servants). Starting in 1914 many of the inhabitants of Aquila worked in the chocolate factory Cima-Norma in Torre Arbeit. In addition the residents also often farmed land and raised livestock. The closure of the factory in 1968 led to a large population decline. In 1990, about 39% of the population worked in manufacturing, while 49% worked in the services sector. About 60% of the worker commuted out of the village.
Ghirone
In 1334, Disentis Abbey acquired rights over all the land in Ghirone. The village was part of the community of Aquila, and in 1803 it merged with the municipality of Ghirone. Then, in 1836, Buttino and Ghirone separated from Aquila and together founded their own community. Buttino was inhabited until the late 19th century and was an autonomous village as far back as the 13th century. The two municipalities rejoined Aquila in 1842 and 1846 and finally separated in 1853. The Citizens Community (Patriziato), which still bears the name of Ghirone-Buttino was founded in 1914.
The Church of SS Martino e Giorgio was first mentioned in 1215 and was rebuilt around 1700. The parish separated from Aquila in 1758 and became independent. As with the other municipalities of the Blenio Valley, much of the population emigrated to other European countries (often as chestnut roaster, servants and waiters). While this was a major source of revenue, it led to a steady population decline. In the late 1950s the Luzzone Dam (1995 and 1999 expanded) was built between the municipalities of Ghirone and Aquila. The dam is used to generate hydroelectric power. The large-scale construction of the dam and the new road tunnel at Toira in 1958, improved the local economy. The new tunnel allowed winter and summer tourism, and the development of a winter sports center (with Campo Blenio) gave the economy a definite boost. Livestock farming, which was for centuries had been the main occupation, however, fell sharply.
Olivone
The political power in the upper Blenio valley was in the hands of a branch of the De Torre family. They owned land in Olivone and possessed the patronage rights in the parish church until the oath of Torre in 1182 ended their supremacy. In 1213 the villages of Olivone and Aquila revolted and united against the Da Locarno family, who had been given power over the valley by canons of Milan. They were able to drive out the Da Locarno's and return to the previous situation, where they were ruled by a governor out of Lombardy. The assemblea di uomini liberi (The Assembly of the Free), which is first mentioned in 1136, provided for the management of common forests, alpine pastures and helped maintain the Lukmanier and Greina passes. By the end of the 14th century the assemblea di uomini liberi took advantage of Olivone's lease on the Santa Maria alpine pasture, which belonged to the abbey of Disentis. The village customary law was written down in the statutes of 1237 and 1474.
During the Early Middle Ages, Olivone was probably the center of a parish that was over the whole valley. Starting in the High and Late Middle Ages, the village's history follows the course of the entire valley. The Parish Church of S. Martino was built before 1136, and in the 17th century, was rebuilt, followed by renovations in 1974 and 1984–91. The church contains frescos from the 17th and 18th centuries. Valuable furnishings and vestments on display in the Cà da Rivöi (Rivöi means Olivone in the local dialect), a building from the 15th century.
