The Teutoburg Forest ( TEW-tə-burg; German: Teutoburger Wald [ˈtɔʏtoˌbʊʁɡɐ ˈvalt] ) is a range of low, forested hills in the German states of Lower Saxony and North Rhine-Westphalia. Until the 17th century, the official name of the hill ridge was Osning. It was first renamed the Teutoburg Forest in 1616 in commemoration of the Battle of the Teutoburg Forest in 9 AD, which most likely took place at Kalkriese instead.

The Sender Bielstein (Transmitter Bielstein) is an FM- and TV-broadcasting facility on the 393-metre-high Bielstein mountain in the Forest of Teutoburg, North Rhine-Westphalia, Germany. Bielstein transmitter, which is the property of Westdeutscher Rundfunk and used for transmitting its programmes was established in 1951. It used until 1954 a 60-metre-tall mast. This mast was replaced in 1954 by a 102-metre-tall antenna tower. However this mast was not able to supply the whole area with FM and TV-programmes and so a taller antenna mast was soon planned. Finally in 1968 construction work started for a 298-metre-tall guyed steel tube mast. This mast, which was completed in 1970 enabled a satisfactory supply of FM- and TV-programmes in the area. On January 15, 1985, at 6.26 MST as result of too much ice load and great wind-induced stress, one of the upper guys of the mast was torn off. As result the mast bent and cracked 160 metres above ground. Afterwards the rest of the mast collapsed as the falling upper parts destroyed the guys holding its lower parts. Already on the afternoon of that day as replacement for the first FM-transmitter which used the mast went on air again, by using a communication tower of Deutsche Telekom as the transmission site. Three days later, TV broadcasting was also restored. On Bielstein mountain, a temporary 85-metre-tall auxiliary transmission mast for transmitting the TV and FM-programmes was erected. Of course, reception of the signals radiated from this auxiliary mast was much worse than from the former 298 metre mast and so construction work for a new 302-metre-tall guyed lattice steel mast started, which was completed in August 1986. In April 2006 the mast got a new antenna for DVB-T broadcasting, which reduced its height to 290 metres.

Rethlager Bach is a small river of North Rhine-Westphalia, Germany. It flows into the Werre near Lage.

The Senne is a natural region in the Regierungsbezirk of Detmold, in the state of Nordrhein-Westfalen in west-central Germany. It lies to the west of the Teutoburger Forest, and has an area of approximately 210 km2. It lies between the cities of Bielefeld to the north-west, Detmold to the north-east, and Paderborn to the south. Heath, calcareous grassland, and moorland cover most of the area. The river Ems arises here. Flora and fauna are very rich in the Senne, 901 of the 5000 animal and plant species are listed on the IUCN Red List.116 km2 of the Senne and therefore more than the half of it area are taken by the Sennelager Training Area, which is mainly used by British forces. By 2020 all of the planned reductions in British forces had been completed, which now leaves the future of this landscape undecided.

The Sennelager Training Area (German: Truppenübungsplatz Senne) is a military training area in Germany, under the control of British Forces based in Paderborn Garrison. It covers an area of 116 square kilometres (45 square miles), and belongs to the German Government, which discharges its responsibility through its Institute for Federal Real Estate. The area was first used for military purposes at the end of the 19th century. The Field Marshal Rommel Barracks, Augustdorf is located nearby.

The Hermannsdenkmal (German for "Hermann Monument") is a monument located southwest of Detmold in the district of Lippe (North Rhine-Westphalia), in Germany. It stands on the densely forested Grotenburg, sometimes also called the Teutberg or Teut, a hill (elevation 386 m) in the Teutoburger Wald (Teutoburg Forest) range. The monument is located inside the remains of a circular rampart. The monument was constructed between 1838 and 1875 to commemorate the Cherusci war chief Arminius (in German, Hermann) and his victory over Rome at the Battle of the Teutoburg Forest in 9 AD. When the statue was built, its location was believed to be near the original battle site, although experts now consider it more likely that the battle took place near Kalkriese, about 100 km to the north-west.

Bärenbach is a small river of North Rhine-Westphalia, Germany. It flows into the Furlbach near Stukenbrock.
