The most modern of Zabrze's industrial heritage sites, completionists won't be content without exploring this sterling example of coal mining operations from early 20th century. Of the town's three mines open to visitors, Maciej has been developed for tourists the least, giving it an untouched air of authenticity, as if the workers just happen to have the day off. The primary sights are the hoist tower with the original twin-drum hoisting machine by Siemens-Schuckertwerke which visitors have the opportunity to steer themselves. Unfortunately the pithead tower is under repair and can no longer be climbed. Call ahead to arrange a free tour if you simply can't get enough of this stuff.
