Camille Flammarion Observatory, Astronomical observatory and historic monument in Juvisy-sur-Orge, France.
The observatory features a five-meter diameter dome with an innovative opening system, allowing instruments to be moved outside for celestial observations.
Built in 1883 by French astronomer Camille Flammarion, the observatory transformed a former postal relay station into a scientific research center.
The entrance portal displays a golden star and the Latin inscription 'Ad veritatem per scientam', meaning 'Toward truth through science'.
Located at 20 avenue de la Cour-de-France in Juvisy-sur-Orge, the observatory maintains scientific instruments from the 19th century.
The facility includes a meteorological station, agricultural research area, and a park containing century-old trees planted by Flammarion himself.
