Sendenhorst and Albersloh, combined to town Sendenhorst since 1975, can look back on a long and varied history. The beginnings of a continuous settlement go back to the time of the Migration Period.

Around 500 AD, Saxon Peasant warriors started to settle on the Kiessandrücken of Münster, Hiltrup, Albersloh to Sendenhorst. Later generations advanced to the northern and southern neighbouring zones and founded further settlements. When Charlemagne brought Christianity, the Saxon settlement expansion was more or less finished.

The monastery's registers are being recorded at the Ruhr, a lifetime after Christianisation, since 890 and the years of the younger Levy Roll of the neighbouring monastery Freckenhorst. Many of these settlement places have kept its original form of names: Arnahurst (Ahrenhorst), Dunnungtharpa (Storp), Elmhurst (Elmenhorst), Heranhlara (Rummler), Judinashuvila (Jönsthövel), Scandforda (Sandfort) and Wessithi (West); but most of all Seondonhorst, originally a settlement of only three or four farms, in the high Middle Ages, clerical and secular administration centre.
