The upper entrance to the Mont des Arts, opposite the Whirling Ear from A. Calder, consists of an esplanade between two monumental buildings, at the right the Congress Palace (1958), renamed Square, and at the left the Royal Library of Belgium (1969). In the façade of the library the 15th century chapel of the former Court of Nassau is still visible. Below is the Albertina Garden, which overlooks the Boulevard de l'Empereur - Keizerslaan via the terrace with the equestrian statue of Albert I, opposite the statue of Queen Elisabeth.
