Paris Observatory, PSL University

Just a short trip from the bustling heart of Paris lies a serene and historically rich site that has been a cornerstone of astronomical research for centuries. The Paris Observatory in Meudon, known locally as the Observatoire de Paris - PSL, is more than just a scientific institution; it is a testament to human curiosity and the relentless pursuit of knowledge. Nestled amidst the picturesque surroundings of Meudon, this observatory invites visitors to explore the cosmos and delve into a history that spans back to the 17th century.

The Origins of the Paris Observatory

The Paris Observatory was born from the vision of King Louis XIV and his finance minister Jean-Baptiste Colbert in 1667. They aimed to create an observatory equipped with the finest instruments to advance navigation and cartography. This initiative complemented the founding of the Académie des Sciences in 1666, making the observatory a hub for scientific advancement in France. The original site in Paris was designed by the architect Claude Perrault, and it soon became a beacon of astronomical research.

In 1927, the Meudon site was administratively attached to the Paris Observatory. The Meudon site itself has a fascinating history, having been established in 1876 on the grounds of the former Château de Meudon. This expansion allowed for more specialized astronomical research, particularly in the study of the Sun, making it a vital component of the observatory's operations.

The Cassini Dynasty

For the first 125 years, the Paris Observatory was under the stewardship of the Cassini family, a lineage of distinguished astronomers. Giovanni Domenico Cassini, the first director, significantly expanded the observatory's capabilities. His tenure saw the presence of renowned astronomers like Christian Huygens and Ole Rømer. His successors, Jacques Cassini, César-François Cassini, and Jean-Dominique Cassini, continued to build on his legacy, contributing to geodesy and cartography, and firmly establishing the observatory as a leading institution in the field of astronomy.

Exploring the Meudon Site

Visitors to the Meudon site of the Paris Observatory can expect a captivating journey through both history and science.
