[5][6] The municipality was the first place in the world to utilize a hydroelectrical power station in the mining community of Hamn.

The first female pastor in the Lutheran Church of Norway, Ingrid Bjerkås, worked in this parish, starting in 1961.

On 1 January 1902, the southern part of Berg (population: 1,229) was separated to form the new Torsken Municipality.

The official blazon is "Per bend sinister double bevilled argent and sable" (Norwegian: Venstre skrådelt av sølv og svart ved dobbelt lynsnitt).

This means the arms have a double bevilled division of the field running along a diagonal path (bend sinister).

The field above the line has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

The municipality faced the Atlantic Ocean on the west side of the large island of Senja.

The municipal council (Kommunestyre) of Berg was made up of 15 representatives that were elected to four year terms.
