After three and a half centuries of astronomy practiced within its walls - from 1667 till now - the Observatoire de Paris has an incredibly rich scientific and technological heritage. Its history is that of its scientists, its research, its instruments, its buildings and its archives; today’s scientific discoveries will become tomorrow’s historical treasures.
