  1. Initiativkreis Horizontastronomie im Ruhrgebiet Initiative Group Horizon Astronomy in the Ruhr Area Volkssternwarte und Planetarium Recklinghausen Public Observatory and Planetarium Recklinghausen

  2. Idea Templo Quetzalcoatl Caracól Stonehenge Templo Mayor Tenochtitlán VLT – Cerro Paranal Chichén Itzá Silbury Hill

  3. Modern Design • re-naturated artificial hill • coal mining heap – excavation residues • highest point in the Ruhr area (170 m)

  4. Emscher Rhein Ruhr Latitude: 51°34´ N Longitude: 7°10´ E Location

  5. Site • free sight on 360° • mathematical horizon only affected by a few chimneys • heap is still in use • shape can be modified to needs

  6. The Observatory • diameter of plateau 100 m • diameter of arcs 50 m

  7. High Elevation Observations • apparent size of the moon • siderial clock (Polaris)

  8. Daytime Observations summer solstice line (h=62°) winter solstice line (h=15°) sun dial lunar extremes solar extremes line of equinox

  9. Horizon Observations

  10. Horizon Observations

  11. Horizon Observations

  12. precession measurement with  Leo (Denebola) Horizon Observations • verification within 10 years

  13. azimuthal shift of 5´ in 10 years Horizon Observations

  14.   Scientific Education Park • serving many different scientific disciplines • biology unusual micro-climate typical for renaturated heaps • botany • ornithology • astronomy • geology • Old machine halls can be used for exhibitions and seminars.

  15. First realisation • obelisk (Emperor Augustus) • usage manifold • local sun clock • Indian circles (Hindu circles) • analemma

  16. The Synthesis
