Gyttorp is a locality situated in Nora Municipality, Örebro County, Sweden with 661 inhabitants in 2010.

The owner of Gyttorp estate and blast furnace at that time was the district senior juryman Karl Nilsson.

[4] Karl Nilsson died in 1569, but the estate stayed in his family until 1606 when the Swedish state bought it in order to build a small scale military industry at the site.

In 1670 the Swedish state sold Gyttorp to private owners and the water power was now only used for a watermill and saw mill.

Today the explosive factory is owned by the Australian company Orica and the production is concentrated to detonation systems such as Nonel that was invented by the engineers in Gyttorp during the 1960s.
