In the middle of the forest two beautiful ponds between the trees

Then you come from Milsbeek into that beautiful forest (or from somewhere else) and you see those beautiful ponds. Believe me: no photo can do justice to how fairytale-like beautiful this area is. But make no mistake: a lot of what you see here dates from a not so long ago time when this forest was still the domain of a manor house. Apart from a few pieces and remains (such as an ice cellar), Huize Sint-Jansberg, which was decorated with ornaments that came from a Roman villa (which you can read more about) was completely destroyed in 1944. Incidentally, Sint-Jansberg was part of Germany until 1817. And those ponds? The three ponds used to have different functions. What exactly can be read on an information board near the ice cellar and the giant sequoia. One of them already served as a swimming pond. And there are plans to accentuate the cultural-historical elements of all three. But above all, enjoy them very much because they are beautiful, just like the slopes of the forest in which they are located. Really wonderful.

Once upon a time, one of the largest Roman villas in the Netherlands stood here, with a magnificent view of the Maas. And since 1979, this site has been legally protected as an archaeological monument. Above ground, low walls show the contours of the ground and there is a tubular frame as a representation of the main building at the time.

On a small hill you will find the grounds of the former Roman villa. Part of the floor plan is made visible with stone walls and part of the house is represented by a frame, so that you get a good impression of the size. An impressive remnant of local history.
