[4][5][6][7] The borough of Orsoy includes the Orsoyerberg district, as well as the hamlets of Drießen, Plank, Hasenfeld and Milchplatz.

Teutons supplanted the Celtic inhabitants around Orsoy in 750BC and Ceesar invaded the area establishing Roman Rule in the 1st century BC.

Count Johann von Kleve remained the local lord, and the town was governed by 7 aldermen, although it was never granted market rights.

In 1438 Duke Adolf of Cleves had built a second castle and in 1452 records show a teacher (schoolmaster) hired by the town.

The modern fortress was built 1565-1581 by Italian Johann Pasqualini Elder (Responsible for the construction of the second ring ) and funded by Duke William the Rich of Cleves.

In 1666 Orsoy once again came under Brandenburg management, until 1672 when there was a period of French rule, when Louis XIV ordered demolition of large parts of the existing fortifications.

But a fire in 1818 and the Seven Years' War (1756-1763) and the relocation of the Rhine customs duty office to Homberg in 1805 caused the economy to crash.

In 1935/36 the harbor basin was filled in to facilitate extension to the primary school and extend the river dike.
