The Sigiburg was a Saxon hillfort in Western Germany, overlooking the River Ruhr near its confluence with the River Lenne. The ruins of the later Hohensyburg castle now stand on the site, which is in Syburg, a neighbourhood in the Hörde district of Dortmund. Archaeological evidence suggests the site was occupied in the Neolithic era. The hillfort was raised ca. 700 by Westphalian Saxons. During the Saxon Wars, it was taken by the Franks under Charlemagne in 772, retaken by the Saxons (possibly under Widukind) in 774, and taken again and refortified by Charlemagne in 775.

The people killed were forced laborers from France, Belgium, the Netherlands, Yugoslavia, Poland and the Soviet Union, members of the German resistance, as well as ordinary people whose careless utterance was judged to be "the dissemination of the opinion about the futility of the war and the insult of Hitler". The bodies were exhumed on April 19–21, 1945, six days after the US army had taken Dortmund. In 1953 the city of Dortmund approved plans of constructing a memorial place for the victims.

The University of Hagen (German: FernUniversität in Hagen, informally often referred to as FU Hagen) is a public research university that is primarily focused on distance teaching. While its main campus is located in Hagen, North Rhine-Westphalia, Germany, the university maintains more than 50 study and research centers in Germany and throughout Europe. According to the Federal Statistical Office of Germany, it is Germany's second-largest university. The university was founded in 1974 as a public research university by the state Nordrhein-Westfalen and began its research and teaching activities in 1975. It was founded following the idea of UK's Open University to provide higher and continuing education opportunities through a distance education system in Germany. The university awards the same qualifications as other German on-campus universities and maintains the same requirements. Initially, the university had only three faculties with 1,304 full and part-time students, but today the university has developed into Germany's leading institution for distance education and is the only full university in that field with a student body of 83,536 students in the summer term of 2013 and 86,889 students in the winter term 2013/14. Besides the substantial number of off-campus students, a considerable number of full-time postgraduate research students as well as more than 1,800 members of academic and research staff are based on the University of Hagen's main campus in Hagen. The faculties of the University of Hagen award undergraduate, graduate and postdoctoral degrees and enable habilitation. All the degrees awarded by the University of Hagen are equivalent to those awarded by traditional German universities. The University of Hagen awards degrees and does research in the fields of business administration and economics, mathematics, computer science, law, psychology, cultural studies and political science. The university has produced many notable alumni in the fields of law, economics, business and politics, among them two Gottfried Wilhelm Leibniz Prize winners, 1 Gossen Prize laureate, at least 25 university professors, numerous members of the German parliament, and the former Foreign Minister and Vice Chancellor of Germany, Guido Westerwelle. The University of Hagen is a member of the European University Association (EUA), European Association of Distance Teaching Universities (EADTU) and it is accredited by ACQUIN, FIBAA (Foundation for International Business Administration Accreditation) as well as AQAS (Agentur für Qualitätssicherung durch Akkreditierung von Studiengängen).

The Hengsteysee (Lake Hengstey) is a reservoir on the Ruhr river between the cities of Hagen, Dortmund and Herdecke, North Rhine-Westphalia, Germany. It was built in 1929 and is one of five reservoirs on the Ruhr. The reservoir is about 4.2 km (2.6 mi) long and has an average width of 296 meters (971 ft).

The Klusenberg, a hill that is part of the Ardey range, is located just north of the Hengsteysee. There is also a pumped-storage plant on this reservoir (called the Koepchenwerk after Arthur Koepchen), along with a 4.5 MWh grid services battery repurposed from electric cars.Hengsteysee fulfills the following four functions: functions as the lower reservoir of the Koepchenwerk pumped-storage plant performs biological purification of water from the Lenne deposit of sediment from the Lenne venue for water sports and tourism
