Volcanoes can be classified as active, dormant or extinct. There are no active or dormant volcanoes in Poland. But there are three extinct volcanoes. They are Ostrzyca located north of Jelenia Gora; Grodczyn near Duszninki; and Wilcza Góra near Zlotoryja. However, there really is no reason to be concerned, the most recent of these to erupt was Ostrzyca around four million years ago!
