The mouth of the shaft is located 583 m above sea level between Frauenberg Hill and Trojický Hill. The shaft had a rectangular floor plan with wood reinforcement. Nearby is the former operational building of the mine, decorated with a mining motif by an unknown author from 1936.
The shaft began to be dug in 1631 as a ventilation shaft for the mining of the Holy Trinity Hereditary Adit, but after the discovery of rich mineralization on the Ján vein, it was used for mining. This place was known for intense hydrothermal transformation. The wooden reinforcement was subjected to excessive pressure, the shaft body even deviated, and the transport cages were guided diagonally at a certain depth. After two years of digging, very hard rock was encountered, and therefore in 1633, a new shaft with an altitude of 583.28 m began to be dug 40 m higher. In the 17th century, the shaft was connected to the Holy Trinity Hereditary Adit. Later, it was decided to further deepen the shaft to the level of the Ján vein. In 1826, the last deepening of the shaft began with the aim of reaching the level of the hereditary gallery of Emperor Jozef II. This was done in 1836. The shaft reached a final depth of 359,715 m. In addition to mining, the shaft also had a very important drainage function. In 1759, Jozef Karol Hell built two water column pumping machines here. The first was mounted on a surface with a headwater drop of 68.88 m. The waste water from the first machine was the drive water for the second machine. Both machines pumped water from the shaft sump to the level of the Holy Trinity Hereditary Adit, to a height of 137.76 m. Each machine used up 494 m³ of mine water in 24 hours.
In the area of the former Zigmund shaft, the machine room building of the water column pumping machine has been preserved until now. Even today, behind the engine room building, you can still see the ditch that supplied the drive water from the Klinger tank.
In the 18th century, a pumping horse gable stood above the shaft, which performed the function of a reserve pumping device during the period of lack of water for water column machines. In 1865, a new steam pumping machine solved the increased pumping requirements, especially at the time when a part of the Hereditary adit of Emperor František between the Zigmund and Amália shafts was flooded. It was produced by the J. Sigl factory in Vienna. The pumps for this machine were supplied by the ironworks in Hronec. In the second half of the 19th century, the Žigmund mine became the main mining plant of the entire Banská Štiavnica region. This is documented by a very large pile, which is one of the largest in the entire region in terms of volume. After the Second World War, during the major reconstruction of the shaft body itself, an accident occurred in the newly constructed block reinforcement (the majority of the reinforcement in the shaft collapsed). Subsequently, it was decided that the shaft would cease to operate, and in 1964 it was finally closed.
