A 16th-century engineering marvel will guide our way from the river to one of Prague's most picturesque parks. On our tour, I will show you some hidden signs of the tunnel below our feet. You will find a beer garden with a perfect view over the old town, Europe's oldest wooden carousel, the place where the first Czech electric tramway was launched and streets full of garden restaurants. You'll learn where the world's largest Stalin statue was located and why many buildings on our way had to be reinforced with wooden beams.
