One of Europe’s biggest science museums, La Cité des Sciences is located in the ultramodern Parc de la Villette in the 19th Arrondissement of Paris. The museum frequently curates fun math, engineering, technology and science exhibitions designed to pique adults’ curiosity and capture kids’ imagination. Inside the museum, you will find two sections – the first for kids aged 2-7, and the second for kids aged 7-12. Your little ones will find it difficult to leave. So, you need to be patient.
