History
The roots of Avenches go back to the
Celts. A tribe of
Helvetians had built a settlement on the hills of Bois de Châtel, south of the later
Roman settlement.
The establishment of the Roman settlement of Aventicum, which became the capital of the province, took place around 15-13 B.C. The name comes from the Helvetian spring goddess Aventia. Aventicum soon developed into a blooming commercial center with 20,000 inhabitants. The area was plundered by the
Alamann tribe after the fall of Rome in the third century. A new walled settlement was built in the fifth century. Throughout this period, the town remained the seat of a bishopric and had at least two churches (Saint-Martin and Saint-Symphorian). When the bishop moved his seat to
Lausanne in the sixth century, the decline of the city began.
In 1074, the Bishop of Lausanne,
Burkhard von Oltigen founded a new city on the site and named it Adventica, which became Avenche in 1518. In the 11th century, it was surrounded by a wall, and it received city rights in 1259.
A
German name for the town did not appear until the 13th century, and it is neither a translation of the
Latin, nor a germanized form of the
French. In 1266 the form ''Wibilsburg'' appears, and then ''Wipelspurg'' (1302), ''Wibelspurg'' (1458), ''Wiblispurg'' (1476), ''Wiflispurg'' (1548), and ''Wiflisburg'' (1577). This is derived from the personal name ''Wibili''.
The town made a treaty in 1239 with
Fribourg and one in 1353 with
Murten.
With the
Bernese conquest of Vaud in 1536, Avenches came under Bernese domination. In 1798, it became part of the Helvetic canton of Fribourg. In 1801, the population pushed for incorporation into the
canton of Léman in the
Helvetic Republic. With the mediation of
Napoleon in 1803, Avenches became part of the canton of Vaud and capital of its district.
In 1826 a colony of
Jews from
Alsace settled in Avenches. They were primarily horse traders and built a synagogue in 1865. When economic circumstances worsened at the end of the 19th century the Jews left the city and the synagogue, which was no longer in use, was torn down in 1954.
An airfield was built on the flat land north of the municipality in 1910. During
World War I, it served as a military airfield. When the military airport in
Payerne was built in 1921, the field in Avenches was closed.
On July 1, 2006, the municipality incorporated Donatyre vollzoge.
