The Torenmolen Gronsveld is a 17th century corn mill located on Rijksweg in the town of Maastricht. The mill was built in 1623 for Joost Maximilian van Bronckhorst, who was then the Earl of Gronsveld. His name is carved on the memorial at the foot of the mill. The Torenmolen Gronsveld was severely damaged in a fire in 1944, but was restored in 1958. The mill is now ran on a voluntary basis, and is open to the public on the first and third Saturday of each month.
