Pre-History and Roman era Bellinzona has always occupied an important geographic location in the
Swiss Alps. It is situated a few kilometres south of
Arbedo, where the
Ticino and
Moesa meet. Several key Alpine pass routes, connecting northern to southern Europe, including the
Nufenen,
St. Gotthard,
Lukmanier and
San Bernardino, all converge in the area around Bellinzona making it a key trading center. While the region has been occupied since the
early Neolithic age it was not until the late 1st century BC that a fort was built on the massive
gneiss outcropping known as
Castelgrande during the reign of the
Roman Emperor
Augustus. While the fort fell into disrepair in the following centuries, it was rebuilt and greatly expanded in the 4th century AD. During the reign of
Diocletian and
Constantine a chain of castles and watchtowers was built to protect northern Italy from invasion. Bellinzona's location was recognized as a key point in the defenses and a large castle was built on the Castelgrande. This castle, which was capable of holding a
cohort — several hundred men — was tested in 475 when a formation of 900
Alemannic soldiers was defeated by the smaller castle garrison. Following the
collapse of the Western Roman Empire the
successor states, which included the
Ostrogoths around AD 500, the eastern
Byzantine Empire towards the middle of the 6th century, and the
Longobards from 568/70, all took control of Bellinzona and used the Castelgrande castle to assert control of the surrounding passes. Under the Longobards, Bellinzona became the site of a permanent garrison to protect the region from raids by the neighboring
Frankish and Alemannic tribes. The historian,
Gregory of Tours records that a Frankish invasion in 590 ended when it encountered heavy resistance from the Longobard defenders of the castle. According to legend, a
spear thrust from a defender killed the attacking commander and ended the invasion. From Bellinzona the Longobards controlled the traffic on the important trade route from
Varese over
Ponte Tresa, the
Monte Ceneri Pass,
Biasca and finally over the Lukmanier Pass into
Chur. Some researchers believe that Bellinzona may have been the capital of a county that included most of the valleys in
Ticino. The bishop only owned the inner
keep, which became known as the Bishop's Palace. However many of the nobles in the bishop's court commissioned towers and buildings within the grounds of the castle.
Conflicts between the Pope and the Emperor Under the Visconti, Bellinzona flourished and the Castelgrande was expanded. During the
Investiture controversy of the late 11th century the city of Bellinzona with its castle came under the control of the
Hohenstaufens of
Swabia. However, in 1180,
Frederick I (Barbarossa) placed the city under the jurisdiction of the city of
Como. During the second half of the 14th century a long wall, known as the
Murata, was built across the entire valley of the
Ticino, of which the bottom is about one kilometre wide at Bellinzona. This wall allowed Milan to protect and tax the trade route over the St. Gotthard Pass. Throughout the winter of 1499/1500 unrest in Bellinzona grew, until January when an armed revolt of the citizens of Bellinzona drove the French troops from the city. Following the capture of
Ludovico Sforza in April 1500 and seeking protection from France, Bellinzona joined the Swiss Confederation on April 14, 1500. Bellinzona would remain under the joint administration of Uri,
Schwyz and
Unterwalden until the creation of the
Helvetic Republic after the
French invasion of Switzerland in 1798. Now that Bellinzona's castles were no longer needed to defend against the Swiss, the walls were allowed to fall into disrepair. When flooding in 1515 destroyed part of the
Murata the damage was not repaired. Each canton occupied one of the three castles with a small garrison of troops and outdated artillery.
Since 1803 Following the
Act of Mediation in 1803 Bellinzona became part of the independent canton of Ticino, and the castles became the property of the state. Montebello, Sasso Corbaro and the city walls were neglected and were in a serious state of disrepair by 1900. Castelgrande was used as an arsenal and as a prison for the canton. In 1850 the new
Federal Government, concerned over instability in neighboring countries, built a number of defensive fortification along the St. Gotthard pass. The project provided work for many unemployed citizens of Ticino. In Bellinzona the construction included strengthening the wall and building barracks, which were designed to resemble the medieval fortifications of Bellinzona. This fortification eventually became part of the Castelgrande complex. In 1881, the government tried to sell Castelgrande but weren't able to find any buyers. The first attempts to repair the fortifications started around 1900. In 1953, in celebration of 150 years since the founding of the canton, a major repair project started on the castles. However, the largest reconstruction lasted about a decade and finished in 1992. This project, under the Ticino architect
Aurelio Galfetti, repurposed many of the buildings as well as restoring them. For example, the castle grounds became a park and the central halls became museum rooms. Montebello, which had been privately owned by the Ghiringhelli family, was given to the canton and restored between 1902 and 1910. The castle is now home to the
Museo Civico which has a large collection of archeological artifacts. In 1871 Sasso Corbaro was bought by a group and converted into a hotel and later a restaurant was added. In 1919 the canton placed the castle under protection to prevent further modification of the castle. It was restored between 1930 and 1935 and in 1964–97 was home to the
Museo delle arti e delle tradizioni popolari ticinesi. ==Castelgrande==
