Résumé
Montpellier hosted one of the first French observatories, and has therefore a long and rich tradition in the development of astronomy as a research topic or as a teaching subject since the 17 th century. This is the reason why such a large collection of astronomical instruments could be gathered and preserved. Recently, the Science university of Montpellier has worked towards the inclusion of this collection on the French National Heritage List (at least for 56 items out of the 240 listed in the inventory), and some of them have been repaired. You will find below the history of this collection which can be accessed online.
