Funny Roundabout in Rohr

In the Village of Rohr im Kremstal there is a funny roundabout with a nice little castle in the middle. Usualy roundabouts here in Austria are not something special but in Rohr they built a small little castle in the middle of the roundabout, I only know a few roundabaouts with some special regional monument in the middle, the one in Rohr is one of them. I had to stop at the gas station right next to the roundabout so I took some pictures of it. I have seen a lot of roundabout with different flowers planted in the middle or only one tree but Art like this is seldom.
