Kallnach (French: Chouchignies) is a municipality in the Seeland administrative district in the canton of Bern in Switzerland.

[3] Kallnach was the site of a Bronze Age foundry as well as a small Roman era settlement or way station.

The Roman road from Aventicum to Augusta Raurica or Vindonissa passed through Kallnach.

In 1231 the Kyburg ministerialis (unfree knights in the service of a feudal overlord) family of Oltigen and the monasteries of Frauenkappelen, Frienisberg and Tedlingen all owned property in Kallnach.

The ministerialis family of Schüpfen held the low justice right in Kallnach and Niederried.

These properties and rights passed through a number of families until Bern bought the village in 1521–22 and incorporated it into the bailiwick of Aarberg.

[5] The municipality is located on the eastern edge of the Grosses Moos marsh between the Aare river and the Hagneck Canal.

[9] Most of the population (as of 2000[update]) speaks German (1,416 or 96.0%) as their first language, Albanian is the second most common (15 or 1.0%) and French is the third (12 or 0.8%).

[9] The historical population is given in the following chart:[3][13] The entire region around the power plant at Kallnach is designated as part of the Inventory of Swiss Heritage Sites.

[14] Kallnach is considered the longest Straßendorf (a village that lies almost entirely along a single road) in Switzerland.

It stretches along the foot of a moraine of the Rhône Glacier at the edge of the Grosses Moos.

The remains of a Roman road which connected the settlements of Aventicum and Petinesca have been found in the Aspi.

Excavations in 1989 revealed remains which have been variously interpreted as a restaurant, a customs office, or a horse-changing station.

In the seventh century, Romans still lived in the area of today's Kallnach, as evidenced by their remains and graves.

The number of jobs in the primary sector was 67, of which 66 were in agriculture and 1 was in forestry or lumber production.

In the tertiary sector; 65 or 20.1% were in wholesale or retail sales or the repair of motor vehicles, 192 or 59.3% were in the movement and storage of goods, 14 or 4.3% were in a hotel or restaurant, 10 or 3.1% were technical professionals or scientists, 13 or 4.0% were in education and 9 or 2.8% were in health care.

[9] From the 2000 census[update], 96 or 6.5% were Roman Catholic, while 1,206 or 81.8% belonged to the Swiss Reformed Church.

This is followed by three years of obligatory lower Secondary school where the students are separated according to ability and aptitude.
