Zakrzówek Park

This guide to Zakrzówek Park in Kraków opens with a nineteen-year-old forced laborer swinging a sledgehammer in a Nazi-run quarry on the edge of the city, decades before the world would know him as Pope John Paul the Second. It follows the quarry after the machines stopped in 1990, when groundwater slowly filled the pit into a turquoise lake over thirty meters deep. You'll hear about the years when swimmers ignored the warning signs and the lake exacted a cost of its own. Stand at the rail above the water and look for the cliffs he once cut stone from.
