When you approach the Grand Palais from the West Churchill entrance, you can no longer see its magnificent glass roof but its façade is equally impressive with Corinthian columns, copper and stone statues, cherub reliefs plus a 240 foot mosaic. It is not a palace. Instead, it houses both a science and art museum, an exposition hall (Galleries National du Grand Palais), and an event hall (Nef du Grand Palais).
