English: Aerial view of the Heidelberg Königstuhl. The Neckar and the old town of Heidelberg lie in the valley. Halfway up, you can see some buildings of the Schmieder Heidelberg Clinics, Speyerer Hof (bottom edge of the picture). The pink patch in the forest to the left of the centre of the picture is a rhododendron plantation in full bloom; to the left below it, the darker trees are the arboretum with the redwoods. The buildings on the summit in the forest below the antennas are the Königstuhl State Observatory and the Max Planck Institute for Astronomy with the House of Astronomy. Aerial view from a gyroplane; some reflections from the cockpit glazing still present.
