The Kraków Technology Trail, created in 2006, is an urban industrial heritage trail. It connects 17 buildings and complexes with unique historic and architectural value, related to industry, communication, energy production, gas supply, and fire and flood safety, built in the 19th and 20th centuries, designed by the best Polish architects, engineers and building inspectors such as T. Stryjeński, Z. Hendel. K. Knaus, M. Moraczewski, T. Talowski, J. Rzymkowski. Some of the technological landmarks in Kraków were also designed, constructed and equipped with machines by engineers from other European countries, making them a part of the European cultural heritage. Some of the objects along the trail still serve their original purpose, others were adapted for new functions, including public ones.
