The Achterhoek (in English: back corner) is part of the former County of Zutphen, and once belonged to Münster in Germany, in the former county of Lohn. Significant towns include Winterswijk, Aalten, Borculo Bredevoort, Eibergen, Geesteren, Groenlo, Hengelo, Lichtenvoorde, Neede, Silvolde, Varsseveld, Vragender, and Zelhem. After 1326 these areas were added to "Graafschap" (Earldom). Doetinchem, Winterswijk and Zutphen are the largest towns in the Achterhoek.
