The lake and natural site of Årslev Engsø is located 2 kilometres (1.2 mi) northeast of Ormslev, including the historic manor of Constantinsborg.

The area around Ormslev has been cultivated as farmland a long way back, as part of the historic and influential manor of Constantinsborg.

From 1902 to 1956 the settlement of Ormslev became a railway town along the now abandoned Hammelbanen rail road line, and the village attracted some industry, including a grain mill, a dairy and some craftsmen.

Half a kilometre southwest, marl was mined and transported by rail and the local farmers sent off their vegetables to market.

The former train station, situated about half a kilometre northwest of the village on a lower elevation, has since been preserved and restored.
