• Maison des Petits for under-6s opens Tue-Sun 2:30pm to 6pm, free with no booking, last entry 5pm and 30 places, so arrive early on rainy weekends
• Open practice spaces move around, since the halls shrink when a show or exhibition is setting up; staff point out the free areas on the day
• Lunch on site at Quartier Sud (Mediterranean), the Café Caché canteen or the food truck, so a long afternoon needs no packed meal

Le Centquatre is an arts center built around huge covered halls that anyone can walk through. Dancers, jugglers, roller skaters and acrobats rehearse in the open spaces, so kids can watch krump, breakdance or diabolo up close.

Inside, the Maison des Petits is a play and reading room designed by artist matali crasset, with painting and water play for toddlers and a parent. Exhibitions and shows run alongside.
