The Palais de Tokyo is the largest contemporary art center in Europe by exhibition space, and it is also the rawest. It sits in the 16th arrondissement, across the Seine from the Eiffel Tower, in the west wing of a building put up for the 1937 International Exposition. The look is deliberate: bare concrete, exposed beams, industrial space left rough on purpose so the rotating contemporary shows have room to be loud. Entry to the exhibitions is paid, so the budget question is whether the show on at the time is worth the ticket that day.
What does not cost anything is the building and its setting. The forecourt and the wide terrace are free to walk, and the terrace looks straight across the river at the Eiffel Tower. It is a calmer, less crowded place to take that photo than the Trocadero a few minutes up the bank. The bookshop and entrance hall can be wandered without a ticket, and the raw concrete architecture is a real part of the visit on its own. For anyone who does go in, the cost depends a lot on who is buying: French institutions run steep student and youth reductions, and visitors under 18 generally enter free.
Two things make it worth keeping on the list. First, it is one of the latest-closing museums in Paris, open well into the night, so it works as the evening half of a day that spent its daylight on free sights. Second, it sits inside an easy free walking route. The Eiffel Tower and its free Champ de Mars lawns are a short stroll along the Seine, and central Paris is one short metro hop away. Budget travelers who want contemporary and modern art can pair one paid visit here with the Pompidou Centre, which is free on the first Sunday of the month, and treat the Musee d’Orsay as the third stop on a Paris art run.
