Founded in 1937 for the International Exposition of Arts and Technology, the Palais de la Découverte has occupied the west wing of the Grand Palais for nearly 90 years. It was famous for its unique approach — science communicated through live demonstrations by science mediators rather than static displays — and for its planetarium, one of Paris’s most beloved institutions. The museum covered physics, chemistry, mathematics, biology, astronomy, and earth sciences across eight departments.

Palais de la Découverte & the Paris Museum Pass
Paris’s beloved science museum in the west wing of the Grand Palais — with a legendary planetarium and live science demonstrations. Currently undergoing renovation, with full reopening planned for 2027.
🚧 Currently Closed for Renovation
The Palais de la Découverte has been undergoing a major renovation since 2021 as part of the broader Grand Palais restoration project. The permanent collections and planetarium have been closed since then. A partial reopening with temporary exhibitions occurred in summer 2025, but the permanent galleries closed again in October 2025 for final fitting-out works. Full reopening of all permanent collections and the planetarium is now expected in early 2027.
Expected reopening: Early 2027 (planned)
Planning a visit? This museum is not accessible in 2026. Your Paris Museum Pass cannot be used here until the renovation is complete. See the open pass-covered museums below for alternatives.
