WThe Dechen Cave in Iserlohn, Germany is one of the most visited show caves in Germany. It is located in the northern part of the Sauerland at Iserlohn. 360 metres of the 870-metre long cave have been laid out for visitors, beginning at the spot where, in 1868, the cave was discovered by two railway workers.

WThe Fossa Eugeniana or Spanish Rhine-Maas canal was a large-scale ambitious project of the Spanish-Dutch Eighty Years' War planned by the then Spanish regent in Brussels, Isabella Clara Eugenia, after whom it was named, during the years 1626–1630. It consisted of a fortified canal intended to blockade the United Provinces and to divert trade from the Rhine near Rheinberg just south of Wesel and reroute it to Venlo on the Maas, in Spanish territory. The Spanish Rhine-Maas canal had military importance, when at the time Spanish garrisons in north-western Germany reached their maximum extent, amounting to around fifty fortresses and forts. It was to be 25 metres (82 ft) wide, 1.4 metres (4.6 ft) deep and 60 kilometres (37 mi) long. The Fossa Eugeniana was never finished. A 5.7 km section west of Geldern is in use as drainage canal. It is known under the name Grift.
