Rheda-Wiedenbrück (German: [ˈʁeːda viːdn̩ˈbʁʏk] ⓘ; Westphalian: Raie-Wienbrügge) is a city in the district of Gütersloh, in North Rhine-Westphalia, Germany.

The twin community lies within the valley of the river Ems in the Westphalian Lowland south of the Teutoburg Forest, which is about 30 km away.

The formerly independent towns of Rheda and Wiedenbrück are separated by the Federal Highway 2 which does not, however, form the historic border between the two districts.

Close to the public pool in Wiedenbrück, an artificial side arm branches off to the north of the river Ems.

One characteristic of the two combined cities is a green strip several kilometers long along the Ems, starting at Emssee in downtown Wiedenbrück and ending near the water castle in Rheda.

The dendrochronological analysis of two tree coffins found north of the Saint Aegidius church resulted in a dating to the years 907/923 and 926/42.

Emperor Otto granted the rights of market, coin and customs law for Wiedenbrück to the bishop of Osnabrück in the year 952.

In the same year the boundaries between the Office Reckenberg to which Wiedenbrück counted, and the adjacent Rheda were established in the so-called Bielefeld recess, as two independent sovereign areas were first recognized.

The chapter of fellows of collegiate was[clarification needed] disbanded in 1810, and the Office Reckenberg with Wiedenbrück were ceded to Prussia at the Congress of Vienna in 1816 and assigned to the new province of Westphalia.

In the early morning hours of 10 November 1938 members of the SA, who had previously gathered in the adjacent restaurant Neuhaus, set the Rheda synagogue on fire.

The highway was not, as is sometimes falsely claimed built almost exactly on the border between Rheda Wiedenbrück, but crosses it several times in different city areas.

In 1940, Field Marshal Hermann Goering ordered the confiscation of all bronze church bells, which were to be used for arms manufacturing.

Because the district of Gütersloh is a stronghold of the Assyrian people living in Germany, the city has a relatively high share of members of the Syriac Orthodox Church.

The figures up to 1970 and for 1987 are census results [8][9] and from 1975 based on official updates by the State Office for Data Processing and Statistics.
