A large hard coal extraction shaft of the former KWK Pstrowski in Zabrze, with a surviving headframe and winding-engine house, now operating as a drainage pumping station within the Centralny Zakład Odwadniania Kopalń.
Szyb Gigant is located in the Rokitnica district of Zabrze (Osiedle Młodego Górnika), within the former KWK Pstrowski complex. Szyb Gigant is the principal surviving shaft structure of the former Kopalnia Castellengo / Rokitnica / Pstrowski hard coal mine complex in Zabrze. Construction of the shaft began in 1942 during the German wartime operation of the mine with the intention of consolidating the Castellengo and Abwehr (later Mikulczyce) mines.
Its depth was planned at 875 metres. Wartime supply difficulties halted work; sinking resumed under Polish administration in 1946 and was completed in 1951. The winding-engine buildings for the northern and southern shaft compartments were completed in 1952–54, and the first symbolic skip of coal was raised on Miners' Day (Barbórka) 1953.
Through successive mine mergers the shaft became part of Kopalnia Rokitnica in 1970 and KWK Pstrowski in 1973. Following closure of KWK Pstrowski at the end of 1995, the shaft passed to the Spółka Restrukturyzacji Kopalń and became the main shaft of the Pompownia Stacjonarna Pstrowski within the Centralny Zakład Odwadniania Kopalń. It remains the only surviving shaft structure of the former KWK Pstrowski complex.
Note: The supplied town field for this site reads Bytom, but research confirms Szyb Gigant is located in the Rokitnica district of Zabrze (Osiedle Młodego Górnika). The coordinates supplied (50.3402069, 18.8251886) are consistent with the Rokitnica/Osiedle Młodego Górnika area of Zabrze.
The parent mine of Szyb Gigant was founded in 1897 by Count Franz von Ballestrem, owner of the Biskupice estate, under the name Castellengo (from the Ballestrem family's ancestral seat in Lombardy). In 1942, during the German operation of the mine — renamed Castellengo throughout this period — the decision was taken to build a new and large extraction shaft intended to consolidate production from both the Castellengo mine and the neighbouring Abwehr mine (later Kopalnia Mikulczyce). This shaft, named Gigant, was designed to reach a depth of 875 metres and was intended to be the most prominent shaft in Zabrze. Construction began in 1942 but within a year supply difficulties caused by wartime conditions forced a halt. Following the end of the Second World War and the transfer of the mine to Polish state administration in 1945, the mine was renamed Rokitnica. Construction of Szyb Gigant resumed in 1946. Sinking was completed in 1951. The winding-engine houses for the northern and southern shaft compartments were built and commissioned between 1952 and 1954. The first symbolic skip of coal from Szyb Gigant was raised on Barbórka — Miners' Day — in 1953. On 1 October 1960 Kopalnia Mikulczyce and Kopalnia Rokitnica were merged into Kopalnia Mikulczyce-Rokitnica; from 1970 this undertaking was renamed simply Rokitnica, having further incorporated the merged Ludwik-Concordia mine. In 1973 Kopalnia Rokitnica was incorporated into the enlarged Kopalnia Węgla Kamiennego Pstrowski, which at that time became one of the largest collieries in Poland both in terms of mining area and output. KWK Pstrowski completed coal extraction at the end of 1995. From the 1980s onwards, various shafts at the former Pstrowski complex were progressively liquidated. The headframe of Szyb Staszic was demolished on 2 May 2018, leaving Szyb Gigant as the sole surviving shaft of the complex. The Pompownia Stacjonarna Pstrowski, of which Szyb Gigant is the main shaft, operates two shafts — Gigant and Staszic (the latter retained for drainage purposes only, without its headframe) — and its function is to protect neighbouring active mining operations from water hazard by draining the flooded former workings. A 3D photographic survey of the Szyb Gigant engine house was carried out in 2024 by the Śląska Biblioteka Cyfrowa as part of an industrial heritage documentation programme.
