Berg is a municipality in the district of Weinfelden in the canton of Thurgau,Switzerland.

The castle and the rights to rule over the villages of Berg, Andhausen, Donzhausen and parts of Andwil (TG), Mauren and Mattwil were rented out by the Cathedral of Constance (not the Bishop) until 1798.

During the Protestant Reformation in 1529, the village converted to the new religion, while the court and ruler remained Catholic.

Due to the religious tension, regular church services were not held in Berg until 1575.

In 16th and 17th centuries, the Catholic parish also included Altishausen, Birwinken, Dotnacht, Graltshausen, Guntershausen, Hugelshofen and Mattwil.

[3] The majority of the local economy was made up of fruit production along with a distillery, livestock (in 1899 a municipal dairy was built) and until 1900 vineyards.

In 1911, the village was connected to the Mittel-Thurgau-Bahn rail line through stations at Kehlhof and Berg.

More recently, a favorable tax rate and an attractive location, have led to strong population growth and development of new residential areas.
