Fort Hermann
Slovenia
Fort Herman is an Austro-Hungarian fortification built on Mount Rombon, now in Slovenia. Work started on Apr. 9, 1897, and ended in 1900. Fort Hermann is named after Johann Hermann von Hermannsdorf, who died nearby fighting Napoleon’s forces in 1809. Hermann was built to supplement the aging Werk Flitscher Klause, just down the mountain. Fort Hermann was also built to control the Bovec Valley and support Flitscher Klause with artillery. Hermann is designated a fort because it is named after a person rather than a location.
