The mill belonged to the Lordship of Oploo in 1516, the current mill building dates from 1725. Over the centuries, the mill has been used as an oil, grain and hulling mill, currently part of it is in use by the Sint Matthiasgilde. The post mill De Korenbloem is a very old post mill that had two other locations before it was moved to Oploo. Before 1663, this mill was in 's Hertogenbosch. Furthermore, in Oploo you pass a park with a moat in the park. Within the moat there used to be a castle 't Juffere that was probably built around the year 1400. The castle owes its name to three women who were the last to live there. The castle was demolished at the beginning of the 19th century, what remains is the moat with a group of statues of the three last women and an impression of the former castle in the inner courtyard. The Sint Anthonisbos is originally a production forest that has changed through years of management into a very attractive forest area with a centrally located large open heathland, the Ullingse Bergen. On the heathland but also in a part of the forest, Scottish highlanders and sheep graze, keeping the area open. The hike in the Ullingse Bergen passes a sheepfold with often also the flock of sheep in the immediate vicinity. The hike goes through a grazing area where several Scottish highlanders graze.
