The name was derived from the German word Grund that used to mean 'valley'. The name appears in the oldest sources in Latin as vallis beatae virginis, i.e. 'valley of the Virgin Mary'.
The village was probably founded in the mid-13th century by the German miners, when silver was discovered in the area. The first written mention of Grunta is from 1305.
