Certova strouha was built as part of the most interesting dam system in the Krkonose Mountains with a flood prevention function. Floods were a serious threat to locals at the end of the 19th century. Extensive torrent dams and works in the tributary areas of the rivers Labe, Jizera and Upa are evidence of the great skills of our predecessors, and Certova struha is a nice example. It has been almost completely preserved and has been functional for today. The mastery of the building works, with only modest technical equipment available, led to 43 transverse and 194 lengthwise torrent control structures made of stone, where approx. one-half of the stone used came from a quarry opened above the confluence of the Cerveny brook.
An educational trail leads along Certova strouha in Certuv dul to acquaint visitors with this technical monument.
