Královská obora Stromovka

The guide to Královská obora Stromovka in Prague follows two mining crews boring through Letná hill from opposite ends in the 1580s, using nothing but fire and water to crack the rock, on Emperor Rudolf II's order to bring the Vltava River into his old royal hunting park. It tracks the tunnel's fortunes across the centuries after the water finally reached the ponds, through wars, neglect, and a brief public reopening. Walk the ponds and picture the channel running beneath the grass.
