Historic observatory visits




Climb to one of the highest points on the Seine's left bank for a sweeping panorama of Paris and a peek inside a working 19th-century observatory. The Grand Télescope Solaire still scans the sun while visitors wander formal gardens and spot the Eiffel Tower from the terrace.
