It was sunk between 1556-1568 by the geometer Jan Faigl (Fajgl). Thanks to this shaft it was possible to reach the more prosperous western part of the Bochnia salt deposits. In 1792 the shaft reached a depth of 212 metres (the current August level). In 1883 the horse treadmill powered winding engine which had been used up to this time at the Campi shaft top was replaced with a steam engine. In 1996 an electrically driven winding engine was installed.
