Historic shaft site on Potočná street in Štefultov, a former mining settlement within Banská Štiavnica, working name Ignác šachta.
This shaft is located in Štefultov, a mining district forming part of the town of Banská Štiavnica in central Slovakia, within the UNESCO World Heritage area of Banská Štiavnica and the Technical Monuments in its Vicinity. Štefultov was historically a mining settlement where several ore veins were worked, notably the Štefan and Grüner veins, by a series of shafts and adits. The most significant enterprise there was the Friedenfeld mining company, which was later absorbed by the imperial treasury. Named shafts documented in the Štefultov area include the Štefan shaft at 315 metres depth and the Mária shaft at 416 metres depth, as well as the Kornberg adit, recorded from 1584.
The canonical name Ignác šachta has not been confirmed in the principal consulted sources for the area, and headframe survival at this location has not been established.
Štefultov was originally a mining settlement and former suburb of Banská Štiavnica, situated in the immediate environs of the town. The settlement is described in historical records as a predominantly mining community through which the Štefan and Grüner veins passed, both worked by multiple mining works over several centuries. The Kornberg adit, which later served as a drainage adit, was first granted in 1584 and represents one of the earliest documented workings in the area.
The principal mining enterprise was the Friedenfeld company, whose operations in Štefultov were subsequently taken over by the imperial treasury (erár). Among the shafts documented in Štefultov were the Štefan shaft, sunk to a depth of 315 metres from the surface, and the Mária shaft, reaching 416 metres. The settlement was administratively merged with Banská Štiavnica during the 20th century.
As part of the broader Banská Štiavnica mining landscape, Štefultov lies within the protected area inscribed on the UNESCO World Heritage List in December 1993, covering the historic town and the technical monuments of its vicinity. The shaft recorded here as site 838, located on Potočná street in Štefultov, falls within this documented mining zone. Its working designation Ignác šachta has not been verified against published or official sources for the area, and the presence or absence of any surviving headframe or surface structure at this location has not been confirmed from available evidence.
