There is something moral to design things that will last for a very long time, for me it is important to visit the modernists. It is always stimulating and joyfull to visit the permanent collection of the Centre Pompidou.
Climb your way up the escalators to the 9th floor of the Printemps department store (the Beauté & Maison building) for possibly one of the best panoramic views of Paris. You can see pretty much everything from here and unlike the views from the Eiffel Tower you’re right in the middle of the city and can almost reach out and touch the monuments around you. Go up on a sunny afternoon and take a seat on one of the benches, lay down on the fake grass lawn or have a drink and a snack at the Deli-Ciel café.
