Star Trails above Graz

From the photographer: “In this photo you can see the Murinsel (German, literally Mur island), an artificial floating platform in the middle of the Mur river in Graz, Austria. Just above it you can see the Schloßberg literally means “castle mountain”, which describes it exactly. It is a hill topped by a castle, in the center of Graz.”
