Centre national d'art et de culture Georges Pompidou - Pompidou Centre

http://mylittlenomads.com/paris-for-kids
Open daily 11am to 10pm, closed Tuesday
A good mix of indoor and outdoor activities when you’re uncertain of the weather. An indoor kids playground, a modern art gallery (that often has kid-friendly exhibits), a cinema, long glassed in escalators that hug the outside of the building, and a viewing area on the roof. There’s always lots going on here. And be sure to check out the fun and colorful Stravinsky Fountain outside the Pompidou and surrounded by street performers and cafes.

The Pompidou Center (19, rue Beaubourg, Fourth Arrondissement) has a hands-on children’s area called La Galerie des Enfants, with rotating exhibits designed by artists (one devoted to Frida Kahlo opens in mid-October). It’s free for kids; adults need a museum ticket. Add to that a brief tour of the main collections on Levels 4 and 5, a stunning view across Paris from Level 6, a jaunt through the terrific ground-floor gift shop, and lunch next door at one of the cafes opposite the fantastical Stravinsky Fountain, and you have yourself a très bonne journée.

13. Atelier Brancusi

Immerse yourself in the smooth shapes of Brancusi’s sculpture with a free visit to his recreated studio at the Pompidou Centre. The Romanian-born abstract sculptor made a name for himself with famous works like The Kiss, and this Brancusi workshop is a lovingly assembled and surprisingly intimate glimpse into the mind of an artist.

While a visit to the Pompidou Centre's main museum and exhibitions will cost you at least €10, the studio of Constantin Brancusi, in the same square, is free to visit. The revolutionary sculptor, who died in 1957, left his workshop and all its contents to the state and the Pompidou Centre had the studio taken apart and reconstructed in front of it in a modern pavilion. Visitors can get an impression of the space in which Brancusi worked, as well as see some of the work that helped redefine modern sculpture.

The Stravinsky Fountain was one of the first modern fountains in Paris. In 1983 it was installed at the Place Igor Stravinsky, right near the equally modern and eye-catching Centre Pompidou. It seems fitting that such a modern fountain is located near the most famous modern museum in Paris. Thanks to its colorful and moving sculptures the fountain quickly became a popular sight in its own right.

The Stravinsky Fountain consists therefore of a large shallow rectangular basin adorned with 16 sculpted fountains illustrating Stravinsky’s musical creations.

The Stravinsky Fountain is a shallow basin of 580 square meters located in Place Stravinsky, between the Centre Pompidou and the Church ofSaint-Merri. Within the basin are sixteen works of sculpture inspired by Igor Stravinsky's The Rite of Spring, and his other major works. The black mechanical pieces of sculpture are by Jean Tinguely, the colored works by Niki de Saint Phalle.

This can be surprisingly hard to find if you aren’t properly oriented (it’s in a courtyard). We ended up walking around the entire Pompidou Centre before coming across it. Facing the main entrance of the building, it will be on the right side of the building. It's whimsical and even for those who prefer more traditional art, it's much more pleasing to the eye than the Pompidou Centre itself. If you’re in the area, you may as well stop by, but not worth going out of your way just to see it.
