De Molen van Nijs (also known as De Nijverheid) is a flour mill in Stramproy. It is a round brick belt mill, built in 1903 for Michiel Kunnen. In 1921 the mill came into the hands of Jaques Nijs, who renovated the mill. From about 1960 the mill became out of use and slowly began to show signs of decline. The municipality bought the Molen van Nijs in 1974 and had it restored the following year. The mill is used as an instruction mill and can be visited when it is running.

The Broekmolen van Stramproy was from the beginning of the 19th century always called water-grain mill. The Broekmolen is beautifully but secluded in the hamlet of Heyeroth near Stramproy. A dirt road leads from the paved road to the Belgian town of Bocholt to the mill. The mill from the Aabeek, which forms the border here, receives water for the drive. The area around the mill was originally woody and sparse. Traditionally the mill was a loan from the Stift van Thorn. The mill is driven by a wooden bottom slab with sheet-iron blades. The mill with an interesting history has recently been made ready for use again. The Broekmolen is used for the generation of energy. The mill can be visited every 2nd Wednesday and 4th Sunday of the month from 11:00 - 16:00 or by appointment.
