Cultural roads can also be waterways like the Danube Road. Cultural processes have been developing along the flow of the great European river and the roads by it for thousands of years. Along the Danube you will discover the Srebarna Nature Reserve and the Rock-hewn Churches of Ivanovo in Bulgaria. In the southern part of Romania, around the waters of the Danube, you meet the men performing the Calus ritual dance. You can learn more about the treasures of the Danube Road through a game.
