Almkanal, Medieval canal system in Salzburg, Austria
The Almkanal is a water system that has run through Salzburg since medieval times, partly underground beneath the Old Town. Water from the Königsseeache river has historically powered mills, craft workshops, and later electricity generation.
Construction of the waterway began in the 1130s using materials from Roman ruins of the ancient settlement. The system has remained in continuous use and undergone various modifications to serve changing needs over centuries.
The waterway has shaped how people in Salzburg use and move through their city, serving as a gathering place and recreation route for residents today. Walking along its banks, you notice small bridges connecting neighborhoods and locals stopping to watch the water flow.
The waterway is accessible from several points in the Old Town, especially along the riverside paths open to pedestrians. Visitors should know that some underground sections are not publicly accessible, so viewing focuses on above-ground sections and paved walkways.
At St. Peter's Abbey, water still powers a mill that has continuously supplied a bakery for centuries through its medieval mechanism. This ancient system demonstrates how a simple water-driven device can function across generations.
