Aachtopf historical postcard, 1910
The Aachtopf (German:[ˈaːxtɔpf]ⓘ) is Germany's biggest karst spring, south of the western end of the Swabian Jura near the town of Aach. It produces an average of 8,500 litres per second. Most of the water stems from the River Danube where it disappears underground at the Danube Sinkhole, 12 kilometres (7.5 mi) north near Immendingen and about 14 kilometres (8.7 mi) north near Fridingen. The cave system has been explored since the 1960s, but as of 2020 only a small part has been discovered due to a large blockage after a few hundred metres.
