Tracing a 16th-Century Water Supply Tunnel

Prague's engineering marvels extend far beyond its famous bridges and churches. On this exploration of the historic Rudolph Gallery, you'll follow the path of a remarkable 16th-century water tunnel commissioned by Emperor Rudolph II. This fascinating feat of Renaissance engineering still functions today, carrying water from the Vltava River to feed the lakes of Stromovka Park, just as it has done for over 400 years.

You'll begin near the Vltava River, where you'll see the original tunnel entrance before climbing up Letná Hill. As you ascend, you'll discover ventilation shafts that reveal the ingenious mining techniques used to construct this perfectly sloped water channel. Along the way, you'll be rewarded with panoramic views of Prague's spires and learn about Emperor Rudolph II, whose passion for science, art, and alchemy gave the city its mystical reputation.

You'll walk through charming Prague neighborhoods above the hidden tunnel, spotting centuries-old ventilation chimneys nestled between cafés and restaurants. The journey continues through the picturesque Stromovka Park, once the Royal Game Reserve, before reaching the tunnel's exit at the Water Administrator's House. The tour ends at the park lake fed by the same water system that has flowed continuously since the late 1500s.

On this 75-minute walking tour, you'll have a chance to:

• Visit Europe's oldest preserved wooden carousel, dating back to the late 19th century
• Learn how miners created a perfect water tunnel using multiple ventilation shafts to work simultaneously
• See the site where the world's largest Stalin monument once towered over the city before its dramatic 1962 demolition
• Explore the tranquil streets of Prague's Letná district, known for its picturesque facades and garden restaurants
• Discover the historic Water Administrator's House where you can hear the rushing water through the windows
• Enjoy spectacular panoramic views of Prague Castle and the Old Town from Letná Hill
• Walk through Stromovka Park, a former royal hunting ground transformed into one of Prague's beloved green spaces

Follow this engineering marvel from river to park and discover a side of Prague that most visitors never see, where Renaissance innovation meets peaceful urban nature.
