In 2017 we will celebrate the founding of the Paris Observatory and its historic building. Its walls were raised in 1667, designed and built in accordance with the laws by which is governed astronomy and which are in no way arbitrary. Its venerable masonary has has witnessed the passage of eminent personalities, whose work and discoveries have survived diverse political events, the Revolution and several world wars, and created French astronomy.
