Riddarhyttan is a locality in Skinnskatteberg Municipality, Västmanland County, Sweden, with 431 inhabitants in 2010.

[1] The Swedish national road 68 is running through Riddarhyttan and the lake Lien is located next to it.

When the last ice age in Bergslagen came to an end about 9,500 years ago, Riddarhyttan was located on the border between land and sea.

That gave rise to a red-colour soil in some parts of Riddarhyttan, especially in the area called Röda Jorden (red earth).

Remains of several primitive blast furnaces have been found and the age have been established by carbon dating.
