Hamburg Observatory
The precursor of Hamburg Observatory was a quasi-private observatory by Johann Georg Repsold built in 1802, originally located at the Stintfang in Hamburg. It was built in the city with permission of the Congress. It started in 1803, and had a meridian circle built by Repsold . However, it was destroyed in 1811 by a war. Repsold, Reinke, and J.C. von Hess submitted a proposal to Hamburg for city observatory that same year, to rebuild.
