Ewa Shaft (Szyb Ewa) – Black Trout Adit Entrance

The adit has been open to visitors since 1957. It is one of the attractions of the Industrial Monuments Route of the Silesian Voivodeship. The Black Trout Adit and the underground of the Historic Silver Mine were recognized as a historical monument by the ordinance of the President of the Republic of Poland of April 14, 2004.
The tourist route runs between the shafts "Ewa" (adit shaft no. 13 of the Deep Adit "Fryderyk"; depth 20 m) and "Sylwester" (adit shaft no. 17; depth 30 m). During the trip, which takes place by boat, you can observe the small stalactites that are being formed today and the original parts of the adit sidewalk carved in the dolomite rock.
Visiting the facility begins with going down the winding stairs to the underground marina located in the shafts "Ewa" or "Sylwester" (swing movement). Several dozen meters underground, tourists get into a boat and, under the light of lamps, swim a distance of 600 m - until 2018 the longest underground boat flow in Poland. The guide, pushing the boats away from the side walls, tells about the history of mining in Tarnowskie Góry. Due to the variable terrain profile, the adit is situated at a depth of 20–30 m. The width of the adit ranges from 1.2 to 2.5 m, its height is up to 4 m, and the water depth is from 0.7 to 1 m.
