The town consists of 4 districts: Artefacts from various epoques of the Stone Age prove that there was a settlement in this region.

In the 18th century, metal-working companies such as Neuhirtenberger Kupferhammer, which used the first steam engine in all of Lower Austria in 1836, settled in this region.

In 1844, Berndorf consisted of no more than 50 houses with about 180 inhabitants, when the cutlery factory of Alexander Schoeller and Hermann Krupp was founded.

When the war had ended, the metal company was confiscated by the Soviet Army and incorporated into the USIA.

Because of financial problems of the socialised industries in the 1980s, the Berndorf consortium was spun off and passed into private hands.
