The Bovenrijge Mill is a traditional corn mill located on Boltweg in the town of Ten Boer. It was built in 1903 by G. van Dijk Gammerwolde. The mill collapsed in 1976, following several years of neglect. The Groninger Mill Foundation rebuilt the mill in 1983, and it is now ran by two millers, J. O. Oosterhoff and HJ Wubbolts. The mill is open to the public two days each week, with visits possible on other days by appointment.
