Welcome to the web application of the Dionýz Štúr State Geological Institute (ŠGÚDŠ). The portal provides easy access to historical geological maps, focusing primarily on the territory of Slovakia from the period when it was part of the Austro-Hungarian Empire (until 1918).

How was this portal created?

The basis of the project was the extremely successful DVD Geological Maps of Europe (1780-1918), which was published in 2004 by the Czech Geological Survey in cooperation with the Slovak Mining Institute and the State Central Mining Archive in Banská Štiavnica.

Since this DVD is no longer available today and technology has advanced, we decided to gradually digitally process all available maps and make them available to the general public directly on the Internet.

🤝 Acknowledgements: Many thanks to the Austrian Geological Survey for providing digital copies of hundreds of other old geological maps from the territory of Slovakia.
