Also known as Finderis or Findera (the first mention is in 1396). It was named after an unidentified investor operating as far back as 1366. It was located in the area of the southern wall of the present St. Kinga Oratory. From this shaft salt was intensively exploited even in the XV century. In the next century it only served for draining the Regis shaft and ventilating the Bochneris shaft excavations. It was filled in before 1614.
