Schwedenhöhlen, Underground cave system in Harmannsdorf, Austria.
Schwedenhöhlen is an underground cave system in Harmannsdorf, Austria, formed by several tunnels and chambers dug into loess soil. The passages extend across a larger area and form a branching network of low corridors and small rooms.
The passages probably date back to the 16th century, when farmers dug them into the soft ground. In the 17th century they served as shelter while Swedish troops under General Torstenson moved through the region and fighting took place near Korneuburg.
The name recalls the period when Swedish troops moved through the Weinviertel region and locals sought refuge in the carved passages. Today visitors see how people once sheltered underground and stored provisions without modern tools or solid walls.
The entrances are located near Harmannsdorf-Rückersdorf and are marked with signs. Visitors can obtain further information about opening times and access at the municipal office.
Some chambers have specially shaped niches that farmers used for storing grain or root vegetables. The cool temperature and humidity in the loess soil helped preserve perishable food for longer periods.
