Key features are the horseshoe-shaped staircase (Escalier du Fer-? -Cheval) at the end of the stately Cour du Cheval Blanc; the Renaissance ballroom whose ornate ceiling is reflected in the parquet floor; and the allegorical paintings in the Galerie Francois Ier.
The decorative architecture is one of the key features, along with the art.
The floor of the Renaissance ballroom is made of porcelain tile.
