Dotzigen is a municipality in the Seeland administrative district in the canton of Bern in Switzerland.

[3] The earliest trace of settlements in Dotzigen are six Hallstatt grave mounds on the Dotzigenberg.

[3] The village was along the Büren-Aarberg road and the inhabitants traded produce to those towns and operated a rest station.

The Jura water correction projects of the 19th century helped prevent flooding and destruction in the village.

Easy transportation links allowed commercial and industrial developments in Dotzigen.

Despite the presence of an agricultural cooperative and a metal foundry, in 2000 over two-thirds of the labor force commuted to towns such as Biel, Lyss and Grenchen.

The historic Schlössli outside the village was built in 1898 by the brick manufacturer Johann Schaller.

The Jura water correction made possible the expansion of the town in the flat area of the municipality.

[6] The blazon of the municipal coat of arms is Gules in a Chief Argent a Mullet of the first.

[10] Most of the population (as of 2000[update]) speaks German (1,304 or 93.7%) as their first language, French is the second most common (21 or 1.5%) and Italian is the third (13 or 0.9%).

The historical population is given in the following chart:[3][13] Jeremias Gotthelf mentioned the sour Dotziger wine in one of his books, which grew and continues to grow at the foot of the mountains.

At the foot of the Dotzigen Mountains is a small castle, known for its gilded copper roof.

At the exit of the town in the direction of Diessbach is an old flour mill powered by a water wheel.

In the tertiary sector; 259 or 70.6% were in wholesale or retail sales or the repair of motor vehicles, 17 or 4.6% were in education and 76 or 20.7% were in health care.

[10] From the 2000 census[update], 165 or 11.9% were Roman Catholic, while 1,032 or 74.2% 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.

Following the lower Secondary students may attend additional schooling or they may enter an apprenticeship.

Today the trains run only to Büren an der Aare, or Kerzers on the other side.
