Heimberg is a municipality in the administrative district of Thun in the canton of Bern in Switzerland.

By the Middle Ages the village existed and was ruled by the Freiherr von Heimberg.

In 1259 Buchegg donated their portion to Interlaken Monastery but the Kyburgs retained their half ownership and, apparently, full control over the village.

After a failed raid on Solothurn on 11 November 1382 and the resulting Burgdorferkrieg, the Kyburgs lost most of their lands to Bern in 1384.

The city of Bern then passed the half portion of the village to the Bernese Schultheiss Ludwig von Seftigen to rule as a private dominion within the Steffisburg court under the Thun District.

Presumably after the 1528 conversion of Bern to the new faith of the Protestant Reformation and suppression of Interlaken Monastery, the two halves of the village were combined.

[3] For most of its history Heimberg consisted of scattered farm houses in the floodplains of the Aare, Zulg and Rotache rivers.

The swampy valley floors provided rich soil but very limited space.

At around the same time the construction of the Bern-Thun road and the Burgdorf-Thun railroad connected the village with several nearby cities.

The road and navigable Aare river brought about 80 import/export and transport companies to Heimberg in the mid-19th century.

After World War II the population of Heimberg expanded rapidly and new developments sprang up around the old village, including Hubel-Bäumberg and Kaliforni as well as the Winterhalde industrial park.

The rest of the municipality is 2.02 km2 (0.78 sq mi) or 37.1% is settled (buildings or roads), 0.10 km2 (25 acres) or 1.8% is either rivers or lakes.

[6] The blazon of the municipal coat of arms is Azure a Lamb passant Argent holding a flag of the same cross Gules with Tassels Or on a Mount of 3 Coupeaux Vert.

[9] Most of the population (as of 2000[update]) speaks German (5,153 or 93.2%) as their first language, Albanian is the second most common (64 or 1.2%) and Italian is the third (55 or 1.0%).

In 2012, single family homes made up 60.8% of the total housing in the municipality.

[9] There were 3,050 residents of the municipality who were employed in some capacity, of which females made up 43.1% of the workforce.

In the tertiary sector; 620 or 56.4% were in wholesale or retail sales or the repair of motor vehicles, 20 or 1.8% were in the movement and storage of goods, 65 or 5.9% were in a hotel or restaurant, 64 or 5.8% were technical professionals or scientists, 52 or 4.7% were in education and 114 or 10.4% were in health care.

[23] From the 2000 census[update], 3,737 or 67.6% belonged to the Swiss Reformed Church, while 647 or 11.7% were Roman Catholic.

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.
